Crank Length on track

[Allister]

is this from the same folk that say you can't ride a flip flop hub with two sprockets ?

I am all for evidence based safety measures especially when cycling is a comparativley high risk sport compared to pool, but I do think the risk asssessment process should be made transparent along withthe evidence.

Let the discussion continue....

What about carbon fork columns ?

I've got 167.5's but I've also happily ridden 177.5's just got to go fast enough I don't think its an issue with modern low profile pedals.

Having said that once watched a 13 year old 7 stone girl hit her pedal every revolution going just more than walking pace at Calshot. She didn't fall off though.

to solve such problems all riders should have their bike checked prior to riding the track like the kids do at track league

yes it would take longer to get a session started but this is needed having seen the idiots that get let on sqts

on this same subject more needs to be done to check all riders are of a sufficient standard to ride the track having passed their accreditation as you are much more likely to be taken out by some fool who can't ride in a warm up line etc or constantly backpedals etc etc than on the rare ocassion when a rider has an illegally spec bike

if we're going to having emails sent round dictating rules to us like this then we also need greater rider ability standards for training sessions/sqts as the accreditation at present is not sufficient to guarantee a rider is safe enough to ride the track

the coaches are great, just think it needs to be made harder to get the accreditation

I ride an old classic, built way, way before Manchester velodrome was ever thought of.

cranks are 165 but BB height is 10 5/8"
I can ride slow enough for the wheels to be starting to slide with no hint of pedals touching.

that one does make abit of sense. I had a ticking off for that one. wipped the flip or the flop sprocket off. Job done.
You don't need a spare sprocket on the bike weighing it down

That's true, the 14 grammes saved by removing the sprocket is no longer holding me back.

The point I was asking is what is the reason for having to remove the sprocket ?

Is it to save the weight or is it for another reason and if so what is the reason and what is evidence for it ?

It would be good to know the reasoning behind the requirements.

Back on the cranks topic: I agree that clearance is seldom an issue with 170 cranks on a modern track frame with a reasonable bracket height and narrow pedals.

I have seen riders using 185mm cranks on Manchester and that does reduce the clearance significantly but they still get to race on that equipment as there seems to be no rule saying you can't.

I only put my 165 on when i go Calshot all other tracks 170.

I got round Calshot on 170s with no problem on Legros trip last year.

Given my frame is fairly venerable (Richard Kennison's from mid 80s) and was obviously built for use with Campag Pista pedals, this is hardly surprising as modern pedals must have more than 5mm more clearance.

P.S. Why did track pedals have the quill missing. It's not the quill that grounds.

I grounded my Campag Record Piste pedal at Leicester years ago, on 165mm cranks - modern pedals do give an awful lot more clearance!

if you have been on private sessions, or raced there its fine, SQT you need accreditation insurance etc
