How apartheid killed Johannesburg's cycling culture | Cities | The Guardian
What happened to Johannesburg’s once vibrant commuter cycling culture? The dominance of the automobile marginalised the bicycle in many cities around the world through the 40s, 50s, 60s and 70s but that process was accelerated in South Africa by apartheid. When policies of spatial segregation forcibly moved black people to faraway townships at the periphery of the city, the distance between work and home increased dramatically and cycling collapsed as an everyday practice.

Twenty-five years after apartheid’s fall, those spatial and economic inequalities remain entrenched in the city and continue to shape how people get around.

Surgeon's anger at Hammersmith Bridge closure after patient died while he was stuck in traffic - MyLondon
For Martin Hayward, a cardiothoracic surgeon living in Barnes, it has drastically increased his journey times when he is called to perform life-saving surgery.

“Cardiothoracic surgeons are a specialist service. We're only in 28 hospitals across the whole country and there’s not many of us in London. So we’re on-call all the time,” said Mr Hayward.

Many of the call-outs are to the National Heart Hospital in Westmoreland Street, central London. But occasionally he’ll need to drive to Barnet Hospital, or The Whittington Hospital in Highgate, journeys which he now says are a “nightmare”.

“I have to go in once a fortnight, either for a stabbing or a cardiac arrest. Those journeys are now genuinely a nightmare thanks to having to fight through all the traffic.”

Cyclist numbers fall across England as roads are ‘too dangerous’ to ride | London Evening Standard
Eleven per cent of adults in England cycled once a week in 2017/18, down from 12 per cent in 2015/16 - a “statistically significant decrease”, according to the Department for Transport report.

The City of London saw the largest decrease in the proportion of weekly cyclists, from 22 per cent to 11 per cent.

The government analysis also shows men cycle more often and further than women and adults in their 40s cycle the most.

In 2018, men made 15 more cycle trips than women and cycled almost four times further.

Transport for London unveils changes to Chiswick High Road section of planned cycleway |
Cycleway 9 from Brentford to Kensington Olympia that have been made following pressure from opponents led by Conservative councillors from the Chiswick wards of the London Borough of Hounslow.

Work on the 7-kilometre route, which will ultimately be extended westwards to Hounslow, may start later this year following changes to the design following a public consultation that found most respondents in favour of the proposals, says TfL.

Earlier this year, in response to feedback on two specific locations – the Duke Road and Duke’s Avenue junctions with Chiswick High Road, pictured above, and at Kew Bridge – TfL opened a second consultation on revised plans.

It now says that the Kew Bridge junction will proceed as outlined in that second consultation, while changes will be made to the junctions in Chiswick after considering further responses on that location.

Faits divers : Le voleur de vélo est rattrapé par des passants et livré à la police
Mardi, en fin de matinée, vers 11h, une cycliste de 63 ans circulait dans le centre-ville de Toulouse. Jusqu’à ce qu’elle se fasse dérober son vélo par un homme, qui a pris la fuite sur l’engin.

Alertés par les cris de la sexagénaire, des passants ont décidé de pourchasser le voleur dans les rues de la Ville rose en se lançant à pied à ses trousses. Certainement surpris d’être suivi, le malfaiteur a perdu le contrôle du vélo et est tombé à proximité de la place du Capitole.

Rattrapé par les passants, il a été maintenu sur place jusqu’à l’arrivée de la police municipale. Cet homme de 37 ans a été interpellé et placé en garde à vue. La cycliste devait porter plainte.

Rebel Metropolis | It’s Time to Stop Sharing the Road
Stand your ground.

Liberation theories vary depending on the discipline, but most include language recognizing true emancipation can never come from above, liberation can only be derived from the self. Another major component is addressing the socializing that places normalcy on the state of oppression, or even places blame on the oppressed for their condition. How many times have you read a comment claiming if a cyclist gets killed by a car, it was their own foolish fault for getting in the way? And how many times have you witnessed people calmly appeal to said commenter’s empathy, only to watch them predictably prove they have none?

Even more horrifying, if a driver does in fact kill a person walking or biking, they’ll likely be conditioned to believe they were in fact the victim. A recent Op-Ed in the always anti-bicycle Oregonian by a woman (who previously drove her SUV into a man and killed him) warned people on bikes to watch out – she’s killed before, she just may kill again! Even though no bikes were involved in her lethal act of driving that day, bicycles and the people who ride them are now apparently the target of this woman’s misplaced guilt. Such is the pathology of entitlement that so many drivers adopt.

(20+) Livreurs à vélo : «La canicule, c’est vraiment pas grand-chose comparé à tout le reste» - Libération
Ce jeune Congolais, au sourire aussi rayonnant que l’impitoyable soleil qui l’épuise aujourd’hui, ne quitte pas des yeux son vélo électrique, «ma femme», plaisante-t-il. «Je dors avec, sans lui je ne suis rien.» Car au-delà de la chaleur, qui ajoute à la pénibilité de la tâche, le vrai problème des livreurs, c’est le vol de leur outil de travail. Casimir, Ivoirien, dit ne pas comprendre qu’ils soient la cible des voleurs. «On est déjà pauvres et en plus on nous vole nos selles, nos pneus, si ce n’est pas le vélo tout entier. Alors la chaleur, c’est le dernier de nos soucis.»

The Transcontinental Race is the definitive self-supported bicycle race across Europe.

At the sharp end it is a beautifully hard bicycle race, simple in design but complex in execution. Factors of self reliance, logistics, navigation and judgement burden racers’ minds as well as their physiques. The strongest excel and redefine what we think possible while many experienced riders target only a finish.

long distance - How come pairs are slower than solo riders at the Transcontinental Race? - Bicycles Stack Exchange
I expect that the three main contributors are:

The solo riders are just stronger. There's more glory in the solo win so, if you are strong enough to, say, come in the top five on your own, it's probably better to do that than come in the top five as a pair. For example, compare tennis: the really strong players concentrate on singles.

It's easier to look after yourself and know your own limits than try to figure out what your partner's limits are. At this level, the question isn't so much "Can I ride for another hour?" but "How motivated am I to ride an extra hour even though I feel like crap, and can I keep this up to the end?" It must be very hard to figure out exactly where on the scale your partner is.

For a trivial example if this, how often do you end up in the following situation? You and your partner/friend want to go out for a meal. You suggest restaurant A, they suggest restaurant B. You end up saying, "No, no, it's OK, let's go to B" while they're saying, "Really, A is fine. Let's go there."

Drafting doesn't give you much at the kinds of speeds the riders are doing. The winning average speed (based on Wikipedia's statement that the race is about 3900km; averaged over moving time) was only about 23km/h (14mph); the leading pair was at about 19km/h (12mph). So, in reality, the solo riders go at their own speed; the pairs go at the speed of the slower member.

Is hiking alone always faster? - The Great Outdoors Stack Exchange
Suppose you need to cover a fairly long distance (e.g. 30 km) in a moderately difficult hiking terrain (no climbing), in 1 day. You can either go alone or with someone, or with a group.

I think (from experience) that alone is always faster. Is it right, and if yes, why? What are the factors that make me waste time? How much time should I expect to waste? Let's eliminate physical fitness differences for the sake of argument.

If the answer is no (i.e. group hiking time is the same or better than alone time): How can I achieve the fastest group hiking time -- which typical time wasters to avoid, and how?

Having both made unsuccessful solo applications for the fifth edition of the race, Jonathan and James applied and were successful in their pairs entry for TCRNo6. When first introduced as a category in 2014 there was concern amongst racers that pairs would benefit from advantages over solo riders, they can draft as a pair, share equipment and support each other through difficult times. However, it has since become obvious that riding as a pair has its own disadvantages that generally sees solo riders filling the top ten finishers.

Between 2007 and 2010 the city of Seville spent €6.7m putting in 142km of segregated cycle lanes, mainly on sidewal…

There has been lots of talk about the good results of Seville’s Cycling Plan 2007-2010. Among the advantages commonly granted to the cycling promotion model use in Seville, these are the main three:

Increase in the number of bicycle users
Reduction in car usage
Reduction in bicycle accidents

The scope of Seville’s Cycling Plan was to build a 142 km long network of segregated bike lanes. Practically all of them were at sidewalk level, having two directions of traffic (bidirectional), 1,25 m wide per direction and using the same road intersections as pedestrians. The cost of building this network was 35 million Euro (250,000 Euro per km) (El País, 11 May 2014). Moreover, the total estimated four-year cost for the plan’s management was 6.7 million Euro divided into:

ten specific projects about traffic education, health, etc. (4.9 million, 73.2% of the budget)
infrastructure maintenance (662,000 Euro, 9.8%)
“Oficina de la Bicicleta” (Cycling Office) (234,000 Euro, 3.4%)
Civic commision (234,000 Eur, 3.4%)
Bike parkings (162,000 Eur, 2,4%)

iamnotacyclist: A little bit about cycling facilities from LCC Camden
This discussion could be one of the most important that LCC has faced and it is now an appropriate time to review our attitudes to cycle engineering given the potential for support for some serious cycling provision in our capital city now that we have a London-wide local authority.
It seems to me that the arguments put by some LCC members against segregated facilities fall into two groups: 1) specific failings that are due to poor design, legal uncertainty, poor maintenance, etc. 2) points of principle such as the view that cycling in segregated facilities reduces the ability of cyclists to cope with motor vehicle traffic. A related argument puts forward the idea, in John Franklin's words in the semi-official manual, Cyclecraft, that "facilities segregated from the carriageway mainly benefit riders who fear motor traffic"1.

12 tips for better braking |
You’ve probably heard that you should do all your braking before the corner and none while you’re actually cornering, and we’d agree that that is a decent policy. However, sometimes you need to continue braking on downhill corners (particularly hairpins) or you’ll pick up too much speed to get around. Also, you’ll sometimes find that an unknown corner gets tighter as it goes on, or you’ll simply misjudge a corner and find that you’re travelling too fast when you’re halfway around; we all make mistakes.

If you do need to brake while cornering, try to do it while your line is as straight as possible. Any braking needs to be smooth and light because it’s much easier to slide than when your bike is straight and upright. Using both brakes reduces the possibility of a wheel skidding and you coming off.

Why Bradley Wiggins is so wrong: Part One: Sport, Transport and Role Models | Road Danger Reduction Forum
With a love of cycle racing comes an acceptance of crashing. ( Minute remnants of my skin are no doubt lodged in the debris of the Eastway cycle circuit which was destroyed to make way for the Olympic Velodrome). In this year’s Tour de France, of the 45 withdrawals at least 20 were due to sustaining what we classify as “Serious Injury” (SI) That’s about 10% over the three weeks. Although this year may well have been worse than previous ones, this amounts to something like 10% over some 80 hours, equivalent to about 4 months of typical commuting for an urban cycling. As Wiggins’ Team GB team mate David Millar puts it: “Cycling is such a stupid sport. Next time you are in a car travelling at 40mph think about jumping out – naked. That’s what it’s like when we crash. ”
To translate that into London cycling terms, that would result in some 30% of London’s daily cyclists being Seriously Injured every year – about 75,000. Instead there are some 300 – 200 times less. Even allowing for non-reporting, we have a difference of dozens, if not a hundred times less. If we used the (I think less valid) exposure measure of distance, it would still be the case that Tour de France riders are far, far more likely to suffer SIs in conditions where they rarely hit a motor vehicle than people cycling in London.

Every Study Ever Conducted on the Impact Converting Street Parking Into Bike Lanes Has on Businesses - CityLab
But here's the thing about the "studies on possible economic impacts" requested by retailers on Polk Street, or really wherever bike-lane plans emerge—they've been done. And done. And done again. And they all reach a similar conclusion: replacing on-street parking with a bike lane has little to no impact on local business, and in some cases might even increase business. While cyclists tend to spend less per shopping trip than drivers, they also tend to make more trips, pumping more total money into the local economy over time.

Do we ‘know’ what other cyclists are about to do? | Mindwise
In a computer-based survey, we tested whether cyclists are capable of predicting the intentions of a lead cyclist based on only the cyclist’s behaviour before making a turn (Westerhuis & De Waard, In Press). We asked 108 participants to view 24 videos of a cyclist near an intersection on which he or she either turned left, right, or continued straight forward. The videos were recorded in real traffic and the cyclists did not know that they were recorded (they were somewhat stalked), as the situation would have been acted otherwise. We only showed videos in which the cyclists did not use an arm to point out their intended direction (which was the majority of footage). Just shortly before the cyclist actually made a turn, the image was frozen and the participants answered several questions. The first question was ‘which direction do you think that the cyclist will go: left, straight, or right?’. Hereafter, they were asked to provide the most prominent behaviour that made them believe that the cyclist would go in that direction.

The results indicate that the participants’ predictions were only more accurate than chance level for the occurrences in which the cyclist went straight on (Westerhuis & De Waard, In Press). When the cyclist in the video made a turn, this was not predicted more accurately than one would expect based on chance. Furthermore, the predictions of experienced cyclists were not better than the predictions of inexperienced cyclists.

A view from the cycle path: electric cars
It made me think: what exactly have we bought today ? Our tank full of fuel came to a bit more than 36 and a half litres. 36.5 l of petrol weighs about 26 kg. Burning that one tank full of petrol will put about 84 kg, a little more than my own weight, of CO2 into the air. That's the effect from just one tank full of petrol, which according to the manufacturer is supposed to be enough to drive around 500 km.

Petrol is amazing stuff. It has an energy content of 9.7 kWh per litre, so today we bought 355 kWh of energy for our 53 euros. The car consumes about 0.7 kWh produces 0.17 kg of CO2 per km driven.

A few years back, someone who set a world record by cycling over 1000 km in 24 hours calculated that his average power output was about 115 W for the entire 24 hours. That's someone at the absolute peak of what is possible, and his body generated about 2.7 kWh over a 24 hour period.

In light of this, I think it's reasonable to say that an averagely strong person doing an 8 hour shift at a physically demanding job would expend no more than 1 kWh per day at work, so we could say that in our tank full of petrol we've bought the equivalent of someone working hard nearly every day for an entire year, including weekends and almost all holidays. This cost just 53 euros. That really is a bargain.

PsyArXiv Preprints | Bicycle helmet wearing is associated with closer overtaking by drivers: A response to Olivier and Walter, 2013
There is a body of research on how driver behaviour might change in response to bicyclists’ appearance. In 2007, Walker published a study suggesting motorists drove closer on average when passing a bicyclist if the rider wore a helmet, potentially increasing the risk of a collision. Olivier and Walter re-analysed the same data in 2013 and claimed helmet wearing was not associated with close vehicle passing. Here we show how Olivier and Walter’s analysis addressed a subtly, but importantly, different question than Walker’s. Their conclusion was based on omitting information about variability in driver behaviour and instead dividing overtakes into two binary categories of ‘close’ and ‘not close’; we demonstrate that they did not justify or address the implications of this choice, did not have sufficient statistical power for their approach, and moreover show that slightly adjusting their definition of ‘close’ would reverse their conclusions. We then present a new analysis of the original dataset, measuring directly the extent to which drivers changed their behaviour in response to helmet wearing. This analysis confirms that drivers did, overall, get closer when the rider wore a helmet.

First British Soldier Killed In Action During WW1 Was Reconnaissance Cyclist
He was a reconnaissance cyclist in the 4th battalion of the Middlesex regiment. There were a great many cyclist casualties during the First World War because there were a number of cycling regiments, including the London Cycle Corps, the 26th Middlesex battalion and the 8th (Cyclist) Battalion of the Essex Regiment. Personnel from Britain's Automobile Association (AA) made up two companies of this last regiment...

One of the cyclist dispatch riders used by the German army was Adolf Hitler. As shown by his military records he was a bicycle messenger during the First World War. The records says he was a “radfahrer,” a cyclist. If he had been a motorcycle messenger his records would have stated he was a “Kradfahrer.”

The 25-year-old Hitler was a bicycle messenger for a Bavarian regiment, taking messages to the fighting units from the command staff. He was always keen to volunteer for dangerous assignments and – sadly, for later world history – he led a largely charmed cycling life, avoiding death on numerous occasions.

Electric Bikes for Fitness - Training With E-Bikes
Getting an e-bike can dramatically increase how often you ride, according to a recent survey of nearly 1,800 e-bike owners in North America. Before owning an e-bike, 55 percent of the respondents said they rode daily or weekly. After getting an e-bike, that number soared to 91 percent riding daily or weekly. More striking, 94 percent of non-cyclists rode daily or weekly after getting an e-bike—nearly every single one of them!...

For many e-bike owners, their e-bike doesn't replace their traditional bike; it replaces their car. That same e-bike survey found that owners replaced 46 percent of their car commutes and 30 percent of their driving errands with e-bike rides. All you need is a great commuter bag to carry your stuff, and you’re set. Nobody’s fitness is devalued by that.
E-bike riding delivers health benefits.

If you’re straight off the couch, the health gains of e-biking are significant. In one study, when Colorado University researchers gave otherwise inactive people e-bikes and told them to to ride a minimum of 40 minutes a day, three days a week, the volunteers willingly rode beyond the minimum, boosted their fitness, improved their blood sugar levels, and trimmed some fat in just one month.

Dr. Behooving is creating Essays in Bicycle Urbanism | Patreon

per month
Since 2009 my essays and blog posts have amused and empowered the bicycle advocacy community. I have been motivated by the fact that there simply hasn't been anyone else with a PhD in architecture and urbanism (let alone anyone with my good breeding and literary flare), who shares my conviction that cities should not be designed for enormous machines. Cars and trams in cities, I hope you appreciate, are like chocolate fountains and electric bread knives in kitchens: more trouble than they are worth. In the same way that our kitchens work better when designed around tight rations of tools—our chopping boards and knives, for example—so too our cities would be more efficient if they were designed around bicycles... and not a lot more.

Commentary: Why I stopped wearing a bike helmet | CyclingTips
There is a war unfolding and likely escalating in every American city (and in many other countries, too) as communities struggle to decide what our streets will look like in the future. So many projects that aim to provide safer infrastructure for cyclists and pedestrians face fierce opposition from people who would prefer to maintain the status quo — to maintain the primacy of cars.

The loudest voices in that latter group have a consistent tactic to try to marginalize the pleas of cyclists, and helmets have sadly become part of that conversation. In 2018, riding without a helmet has become the corporeal equivalent of rolling through a stop sign — a symbol that you don’t deserve respect or a seat at the table. Few of these people care about your safety or even the public-health costs of bike crashes — they simply want to thrust responsibility on cyclists rather than give us a safe place on the road, or they want to use the helmet issue to discredit us.

As the superintendent for the area put it: “This offending cohort doesn’t worry about being seen.” They had established a “crime series”, he told me. Officers would be investigating properly now. Why? Might it have been something to do with the mass cycling protest that took place in Manchester on Wednesday night?

Bottom Bracket Basics - Velo Orange
BB threading
Let us begin with the French standard because this is, after all, Velo Orange. The French decided that BB shells should be 68mm wide, threading should be35mm x 1mm, and both cups should tighten to the right. Simple and effective! Of course, VO makes French Bottom Brackets.

The Swiss, improved the French standard by reversing the thread on the drive side. This became the Swiss standard and was adopted not only by Swiss manufacturers but also by a few French companies, notably Motobecane. (Motobecane also used French threading on occasion and later switched to British threading; good luck.) The BB shell is 68mm wide and also threaded 35mm X 1mm; but the left cup tightens to the right and the right to the left.

The reason for this improved standard was that the spinning of the crank was thought to loosen the right-hand thread non-drive BB cups. After a few decades, the Swiss noticed that French cyclists, in fact, were not stopping every few miles to tighten their cups. And so the standard was quietly abandoned. The only Swiss threaded BBs made today are the super expensive Phil Wood units. But VO does have a Threadless BB that is a less expensive alternative.

The French standard was also eventually abandoned and, to the everlasting annoyance of the French and of francophiles everywhere, the British/English (or ISO) standard became the world standard. If your classic frame was made in America, Japan, Taiwan, Germany, or Britain, it almost certainly accepts a English threaded BB. This standard is 1.375" X 24 tpi with the left cup tightening to the right and the right to the left; the BB shell is 68mm wide. All VO frames use an English Threaded BB.

Not leaving well enough alone, some British manufacturers, particularly Raleigh, came up with other standards that are outside of my understanding, as did some old American manufacturers.

Finally the Italians, who we reluctantly acknowledge do know something about bicycles, if only the racing sort, blithely ignored everyone else and stuck to their own standard. The Italian BB shell is 70mm wide and has 36 mm X 24 tpi threading; both cups tighten to the right. VO makes Italian Threaded BBs in sizes to fit our cranks.

some metal-mending epoxy putty (JB-Weld is good) to the threads, before
installing the inner parts. This would cause a permanent lock, so you
couldn't adjust the bearing cups or add grease later. I'd use the
standard putty, not the quick-set type, so I could properly set the
adjustable cup, before it hardened.
If only the right-side fixed cup is stripped, I'd use putty on it only
and the left-side cup could still be adjusted. Grease would need to be
added to the bearing cups, but kept out of their epoxied threads during

Steel bicycle frame repairs
Bottom-bracket threads stripped?

This problem is most likely to occur when working on the bicycle and is much more likely with an aluminum-alloy frame than a steel one. The classic repair is to rethread the bottom-bracket shell to the Italian dimensional standard -- 1 mm larger in diameter than the others -- but this requires professional bike-shop tools and Italian-standard bottom-bracket parts. Some bottom-bracket shells do not have thick enough walls to allow the rethreading. A Velo Orange threadless bottom bracket offers another solution. If only one side is stripped, you could secure the bottom-bracket cup on that side with plastic steel -- same removal issue as with the headset locknut, only worse.

Basic Thread Concepts | Park Tool
There is resistance to turning the bolt, as the fastener gets tighter. Some resistance comes from friction and rubbing between the internal and external thread surfaces. Because of this, it is common to prepare the threads with lubrication. This can take for form of liquid lubrication, grease, or an anti-seize compound. Even liquid threadlockers provide some lubrication during tightening. As a simple rule of thumb, if the thread size is small, such as a derailleur pinch bolt, a liquid lubricant is adequate. If the thread is large or the torque relatively high, such as a pedal thread or bottom bracket, use a grease or anti-seize compound. There are situations, however, where a manufacturer may recommend no lubrication on the fastener. If is useful to lubricate the threads and under the head of the bolt, especially when the bolt head is turned during tightening.

Bottom Bracket Service: Cartridge Type | Park Tool
Begin by preparing the threads of the bottom bracket. A thread locker may be used when the frame shell is steel and the cups are either aluminum or steel lockrings. A mild thread locking compound such as Loctite® #242 that is considered “service removable” is preferred. This means that the parts are removable with normal tools, without taking extreme measures. If no thread locking compound is available, grease threads heavily or ASC-1 Anti Seize Compound. For more on thread preparation see Basic Thread Concepts.

Tool Tips--Installing a Cartridge Bottom Bracket
Velo Orange sells a clever cartridge bottom bracket with expanding sleeves that press against the inside of a bottom bracket shell with damaged threads. This cartridge will work with all common threading standards except Italian, whose threads have a larger diameter than the others. A shim of 0.5 mm or .020 inch steel will probably adapt this cartridge to with an Italian shell. The bottom-bracket shell should be between 68 and 71 mm wide. Some Raleigh bicycles and mountain bikes have a wider bottom bracket shell; the expanders unfortunately can't be extended far enough apart to work with these.

Shimano Road Bike Headsets - the Buyer's Guide, 2015
The 105SC headset is made using steel pieces and an aluminum alloy head lock nut. The head lock nut is silver cast aluminum which is then threaded, with a snap in plastic stem seal. The upper race is cast and threaded steel with a recess for the stamped, silver colored, steel head key washer to make the headset loosening up more difficult. Shimano gives the bearing cups their silver color by enclosing the cup in silver colored plastic. The upper cone race is cast steel with a ground bearing surface that is then painted Black. The fork crown race is cast steel with a ground bearing surface. The 105SC has snap in dust seals located under the bearing cups to protect the bearings against contamination. The two steel bearing retainers each have twenty 4mm ball bearings. This Road Racing headset is made in the 1" size only, has a weight of 116.5 grams, with a stack height of 32.7mm and uses a 32mm headset wrench to tighten both the upper cup and head lock nut.

Hilary Stone Campagnolo Headsets
Stack Height An important consideration with choosing a headset is to ensure that your new headset has a stack height the same or less than your current headset. Before removing the headset measure from the bottom of the fork crown race to the the top of the lower head race where it fits into the head tube. Secondly measure the height from the lowest part of the top frame race to the top of the lock nut. Add the two dimensions you have measured together and that is the stack height of your current headset.Your new headset must not have a stack larger than the old one.
For a frame without a fitted headset measure the length of the head tube (A). Then measure the length of the fork steeer tube from the base of the crown race seat to the top the column (B). Subtract A from B and that is the maximum stack height headset you can use – you can use a headset with a smaller stack height.

Fork Crown Race Seat Diameter and Head tube Insert Race Diameter Campagnolo settled on a standard crown race seat diameter of 26.4mm with an insert race diameter of 30.2mm. Japan with the JIS standard settled upon 27.0mm crown race seat diameter with an insert race diameter of 30.0mm which was virtually identical to that used for the most part in the UK prior to about 1975 unless a Campag headset was fitted. However most frames from the last thirty years use the Campagnolo standard and even the Japanese manufacturers mostly made headsets to the Campag dimensions. If your frame and fork has JIS dimensions it can easily be reamed and cut to accept Campag dimensioned headsets by a good bike shop or framebuider.

Sheldon Brown's Bicycle Glossary St - Sz
The stack height is the vertical space taken up by the headset. With a conventional threaded fork, the steerer tube is longer than the head tube by some amount. If a headset is chosen with a stack height greater than this difference, there may not be enough of the steerer free above the upper bearing race for the keyed washer and lock nut to be installed. In the case of threadless headsets, the stack height also includes the height of the part of the handlebar stem that clamps to the steerer.

Active Recovery Induces Greater Endurance Adaptations When P... : The Journal of Strength & Conditioning Research
both groups performed 6 sessions of 4- to 6 30-second sprints interspersed with 4-minute recovery over 2 weeks. However, only ARG cycled at 40% V[Combining Dot Above]O2peak during the 4-minute recovery periods, while PRG rested on the bike or cycled unloaded. After the 2-week training intervention, both groups improved 10-km time-trial performance to a similar extent (ARG: 8.6%, d = 1.60, p = 0.006; PRG: 6.7%, d = 0.96, p = 0.048) without gains in V[Combining Dot Above]O2peak. However, critical power was increased by ARG only (7.9%, d = 1.75, p = 0.015) with a tendency of increased maximal incremental power output (5.3%, d = 0.88, p = 0.063). During the training, active recovery maintained V[Combining Dot Above]O2 and heart rate at a higher level compared with passive recovery (V[Combining Dot Above]O2: p = 0.005, HR: p = 0.018), suggesting greater cardiorespiratory demands with the active recovery. This study demonstrated that greater endurance performance adaptations are induced with active recovery when performing SIT over a short time frame.

Concrètement, le marquage - "sous une forme lisible, indélébile, inamovible et infalsifiable, en un endroit repérable et visible sans manipulation" précise le texte - devrait concerner seulement les vélos neufs. La technologie, puce ou gravure, sera laissée à la discrétion du constructeur, mais devra être lisible par "capteur optique". L'objectif étant de créer un "fichier national des propriétaires de cycles" pour savoir à qui appartiennent les vélos en circulation.

"Quand vous en achèterez un neuf vous entrerez dans le fichier et quand vous en achèterez un d'occasion, vous aurez une petite formalité administrative à accomplir. Ce sera hyper simple. Cela vous assurera que vous n'achetez pas un vélo volé", précise au HuffPost le député LREM Matthieu Orphelin qui a été l'une des sources d'inspiration du plan vélo.

Why children struggle to cross busy streets safely: New research shows perceptual judgment, motor skills not fully developed until age 14 -- ScienceDaily
New research from the University of Iowa shows children under certain ages lack the perceptual judgment and motor skills to cross a busy road consistently without putting themselves in danger. The researchers placed children from 6 to 14 years old in a realistic simulated environment and asked them to cross one lane of a busy road multiple times.

The results: Children up to their early teenage years had difficulty consistently crossing the street safely, with accident rates as high as 8 percent with 6-year-olds. Only by age 14 did children navigate street crossing without incident, while 12-year-olds mostly compensated for inferior road-crossing motor skills by choosing bigger gaps in traffic.

(Drawing) Rings Around The World: Some simple economics of cycling
One of the benefits of setting out the cycling decision in an economic framework is that it can allows us to estimate the effects of time, cost and comfort, and that in turn should enable us to make better decisions around infrastructure. Right now TfL are really struggling to properly analyse the costs and benefits of cycling infrastructure, apparently because their models don't incorporate any estimates of mode-switching in response to infrastructure changes, so cycling schemes look poor value for money in contexts where few people currently cycle, i.e. where such schemes may be most needed.

But if we can estimate a statistical model of mode choice with three factors (time, cost and comfort), then we can get at the question of how much additional cycling we should expect to see if we change the infrastructure on a particular route in a way that changes one or more of these factors simultaneously. Such a model could be expressed as something like the following:

Pij = axij + byij+ czij

where Pij is the probability of person i choosing to cycle trip j, x is time, y is cost, z is the comfort or cycling level of service, and a, b and c are the relevant elasticities of cycling with respect to each factor. This specification accounts for the fact that infrastructure elasticities will vary by person and by trip, although you could start with some averages.

Saddle Height and Cadence Effects on the Physiological, Perceptual, and Affective Responses of Recreational Cyclists - Alberto B. Kruschewsky, Rodolfo A. Dellagrana, Mateus Rossato, Luiz Fernando P. Ribeiro, Caetano D. Lazzari, Fernando Diefenthaeler, 201
Saddle height influences cycling performance and would be expected to influence cyclists physically, perceptually, and emotionally. We investigated how different saddle positions and cadences might affect cyclists’ torque, heart rate, rate of perceived exertion (RPE), and affective responses (Feeling scale). Nine male recreational cyclists underwent cycling sessions on different days under different conditions with a constant load. On Day 1, the saddle was at the reference position (109% of the distance from the pubic symphysis to the ground), and on Days 2 and 3, the saddle was in the “upward position” (reference + 2.5%) and “downward position” (reference − 2.5%) in random order. Each session lasted 30 minutes and was divided into three cadence-varied 10-minute stages without interruption: (a) freely chosen cadence (FCC), (b) FCC − 20%, and (c) FCC + 20%. We assessed all dependent measures at the end of each 10 minute stage. While there was no significant interaction (Saddle × Cadence) for any of the analyzed variables, torque values were higher at lower cadences in all saddle configurations, and the FCC + 20% cadence was associated with faster heart rate, higher RPE, and lower affect compared with FCC and FCC − 20% in all saddle positions. At all cadences, the saddle at “downward position” generated a higher RPE compared with “reference position” and “upward position.” The affective response was lower in the “downward position” compared with the “reference position.” Thus, while cyclists perceived the downward (versus reference) saddle position as greater exercise effort, they also associated it with unpleasant affect.

Government opens dangerous and careless cycling law consultation |
Alliston, who had been riding a fixed wheel bike with no front brake when he collided with Mrs Briggs in 2016, fatally injuring her, was acquitted of manslaughter but found guilty of causing bodily injury through wanton or furious driving under the Offences Against the Person Act 1861.

The case led to calls for the law to be updated, rather than prosecutors having to rely on outdated legislation in such circumstances and last year the government announced that it was conducting a review of the law.

Announcing the consultation today, transport minister Jesse Norman, who has responsibility for cycling and walking, said: “In recent weeks we have announced a range of measures designed to protect vulnerable road users such as cyclists and pedestrians.

This campaign so obviously ludicrously misses the point, that it's worth considering why a political party would launch it.

The creation of narratives to distract from the central problem is an essential part of the new politics. First masterminded by the Russian political adviser Vladislav Surkov in the 1990s, the essence of the strategy is to create guff in the public attentional space that distracts from any meaningful action that would harm the financial interests of the oligarchs invested in the status quo.

A review of cycling laws is ideal: cyclists are a vocal minority who can be guaranteed to rise to the bait, generating a false debate that avoids the central issues. Meanwhile the 25% or so of the public who have difficulty distinguishing between the numbers 2 (pedestrians killed by cyclists) and 1700 (p̶e̶d̶e̶s̶t̶r̶i̶a̶n̶s̶ people killed by motorists) are left with the hazy impression in their wobbling jelly-brains that cycling is dangerous, cyclists are lawless killers (because why else would they be against this obviously sensible measure), and the party proposing action is protecting the public from a very real menace.


Don't feed the troll. Or if you can't resist, make sure you attack their cynical media strategy as you do so.

On foot or by bike? While Paris walks, Amsterdam pedals
It goes without saying that there is an almost mathematical correlation between urban intensities and transit choices — with the added fact that we now have a much better idea of how to characterize this correlation, at least when it comes to home-work commutes.

This is where we start to penetrate the reasons behind the differences in sustainable mobility between the two cities: Paris, one of the densest cities in the world, is 6 times denser than Amsterdam. If we consider jobs, hospitals, universities, entertainment and other urban amenities, central Paris is 7–10 times more “intense[4]” than Amsterdam.

The study, published in the journal Environment International, also finds that riding an electric bike (e-bike) is associated with a higher BMI as compared to regular cyclists. In ascending order, cyclists have the lowest BMI, then walkers, public transport users, motorcyclists, users of an electric bike, and finally car drivers, who have the highest BMI.

By following over 2000 urban dwellers over time, the team found that men who switch from car driving to cycling for their daily travel lose on average 0.75 kg of weight, with an average decrease in BMI of 0.24. For women, this was a little bit less.

The deaths of men over 65 using electric bikes on Dutch roads have caused the number of cycling fatalities in the country to surpass the people killed in cars.

Official figures from the Netherlands’ central bureau of statistics show a near doubling of deaths on electric bikes in the last 12 months, three-quarters of which involved men of 65 years or over.

In 2017, 206 cyclists were killed in the Netherlands, 17 more than in 2016 and the highest number in 10 years. The same year 201 people lost their lives in cars (30 fewer than the previous year).

A quarter of the cyclists were on e-bikes, which have an integrated electric motor to propel cycles to speeds of around 20mph.

However, if there are protected bike lanes and dedicated bicycle traffic signals and other acknowledgements of my existence, I’ll adhere as closely as possible to the letter of the law—not only because it’s safe and practical for me to do so, but also because I want to show my appreciation for a street design that says “You belong,” not “Adapt or die.”

One of the major contributing factors to saddle discomfort and health issues we did discover was the UCI ruling that saddles were only allowed a tilt of less than 2.5 degrees with a 0.5 degree margin of error. We presented our findings to the UCI and they have since increased the angle of tilt to nine degrees with a tolerance of one degree. This has had a major impact on rider health, for both men and women, across the sport.

Témoignage : Voyage à vélo en solo en Belgique et aux Pays-Bas
Dominique, j’ai 51 ans, je vis en couple, en famille. J’ai toujours aimé me balader à vélo, mais en famille c’est toujours compliqué, parce que j’ai un fils qui n’aime pas trop l’itinérance. Il aime bien le vélo comme effort physique, mais pas l’itinérance. On a essayé un peu, mais ça a toujours été très court parce que tout le monde ne s’y retrouvait pas. Et avec mon mari, on en a fait un petit peu aussi.

Mais j’avais envie de partir toute seule, c’était un peu un défi.

J’ai voyagé deux fois trois jours par le passé, j’avais beaucoup aimé, mais à chaque fois, j’avais eu peur. Et là, comme mon mari travaille à Mayotte et que mon fils est parti là-bas, je me suis dit que j’avais l’occasion de partir. Au départ, je pensais partir un mois et puis au final, j’ai aussi des contraintes comme mes parents sont un peu malades, donc j’ai pu partir quinze jours. Et donc comme je déposais mon fils à l’aéroport au nord de Paris, je m’étais dit que j’allais mettre le vélo dans la voiture – comme j’ai une voiture suffisamment grande pour mettre le vélo dedans – et je vais vers le Nord, longer la mer. Je n’avais pas envie d’être en France, c’était après les élections, je me suis dit « Olala… », j’avais envie de quitter la France, de changer d’air. Donc j’ai déposé ma voiture à Dunkerque. Et j’avais regardé sur Internet, qu’il y avait, paraît-il, l’EuroVelo 12.
