UCI to trial disc brakes?

01 Feb 2015 00:36

At the Ronde van Vlaanderen :o :rolleyes:

Doesn't seem certain that it will happen due to Sram and Shimano not having a same size disc for neutral support, but ****ing come on - One of the biggest races of the year is where you want to test this out?

Same old UCI ****

Because there isn't enough crashes already in Ronde...

Disk brakes for bikes - all kinds of bikes - are a pretty well sorted out technology. Compatibility issues between brands for neutral support aside, I'd think the risk of failure wouldn't be any larger than any other piece of new gear that's being used in any races.

I suspect they like the ronde or even paris roubaix because of the smaller groups? it is a test so don't expect very many riders to have them. they are not being required to participate.

That they are testing is hardly the same old UCI ****.

Same old UCI bashing.

What difference do smaller groups make?

Crashes! Fewer riders in a crash might reduce risks of disk burns or cuts. That said chainrings are pretty sharp too and we don't get as many cuts from them as you might imagine.

One reason CX got disks earlier was the fact they tend to race linear so we don't get big pile ups except for the first lap or so. I just think smaller groups reduces the complexity of potential crashes so if the disks have an effect it will be easier to analyze the effect. OF course f you inly have 8 or 10 riders on disks it might be a Moot point.

When you see the destruction a QR lever not tucked into the rear triangle or inline with the fork can do to flesh in a crash, I dread to think what steel rotors will do. Modulations means nothing when flesh on tarmac is always going to stop more quickly than any braking system would.

Yet again, I think there are bigger things to worry about.

I notice in the recent worlds cx that a lot of riders still use canti's

I like the idea that riders today use a braking system comparable to their heroes of yesterday and the romanticism maintained. Today's rim brakes are already so much better than what we raced on in the 80's anyway - why create difference with a new technology when the primary cause for crashing is the width of the road not the stopping power or lack of it!

Agree with this, and also increased stopping power will not necessarily enhance safety. Where dozens of riders are cycling within a few inches of each other, it could easily create more problems, at least in the beginning.

Add in the relatively slow wheel changes and it's obvious why the pro's aren't convinced. Shimano and Sram must be putting a lot of pressure on the UCI though - imagine how much money they can see rolling in when tens of thousands of amateurs update their entire wheel set and braking system, just to copy the proforessionals.

UCI should turn the pressure back on the manufacturers and tell them that UCI will consider disk brakes only if all manufacturers agree to a compatible system.

You mean like before 11 speed came about? And like they have done with rim widths?:rolleyes:

That's because many riders dont actually see it as a braking contest but as a 1 hour bicycle race. Also it really just comes down to personal preference.

Yes, please, and stick a camera to the neutral service so we can enjoy their chat with riders like Cadel Evans in Sierra Nevada during the Vuelta 2009 :D

I think almost everyone agrees this is not about stopping power but modulation and predictability. wet roads, carbon wheels and even aluminum rims all are different in their performance, any top line road brake has enough ultimate stopping power but even they are different when wet versus dry.

As for risk? less easy to quantify as there are already some very dangerous rings on bikes and I imagine there are a few black scars on more than few legs from chainrings.

I don't think this is true. Modulation and predictability is no different on disk brakes than on hydraulic rim brakes. The major difference is that disk brakes decelerate the bike more quickly than any rim brake (significantly more quickly in some conditions), because of their greater stopping power. This reduces the reaction time of anyone following the rider to apply his own brakes, making it more likely that they won't brake in time. So the ability to stop more quickly has drawbacks as well as benefits.

It certainly has to be all or nothing though. Everyone has to use disk brakes or no-one in a professional peloton. It would be carnage descending a high mountain at the sharp end of a race if half the peloton were able to brake much later going into corners than the other half.
