Discs or no discs for pros
Moderators: robbosmans, Moderator Team
I'd like to see someone like Dan Martin using them and see how his races vs crashes ratio improves.

Nothing we wouldn't have expected http://youtu.be/uHFSSXOSnxs
A great piece but they blew it. They needed to run the same test again but switch bikes. The dude riding the disc equipped bike has much better technique - he drives his body back down more quickly and more completely. Even as tested I thought there would be more of a difference.

Invalid Test. Can't trust the power on their fingers....but I do trust in DATA. Loads cells...controlled environment....then I'll turn my attention to it.

You guys want to know the most powerful rim brakes to date? Check this out!
I modified these Diacompe NGC 400 on my wife's bike with a 2:1 pulley system;
...then I like it so much that I've modified the DA calipers on my Triatlhon bike
I have load cell DATA to prove that they are 2x stronger then standard 1:1 pull.

That is an pretty wild mod. Amazing indeed but perhaps you have too much time on your hands . And why the rear brake (I think that's the rear) in the TT rig?

With passion for something...we always make time. I've added the pulley on all my brakes.

Alternatively, are you capable of consistently braking so hard that the only way to avoid endoing is by decreasing the braking force?
The simple answer is yes.
What's the modulation like when being at that limit?
Seems good to me - never stacked it. As you get to that limit you are slowing down quite a bit, the front end is heavily loaded, giving good front wheel traction, so even though you are already squeezing hard, it takes significant additional force to decelerate ever further. These big differences in hand effort, while taxing the sense of feel in the hand, seem to allow for more "fine tuning". The severe downward force also results in really good feedback about what your front tire is up to grip wise.
I think it is a great exercise to find a 10 or 15 percent grade, get the bike up to 50 km/h and practice how fast you can stop. Seen too many good riders with not the slightest clue of how to use their brakes. I live at the top of a 18% grade. I do this at the beginning of every ride. (My cool down at the end of the ride sucks though )
My experience is quite different: I don't remember ever being in a situation where I felt I would lose the front wheel or flip over it if I squeezed any harder while braking hard on dry pavement (weight as far to the back and as low as possible, of course). I also find the modulation to be quite bad when near the limit. It is hard to brake harder, but it is also hard to ease off just a little, which results in jerky braking. For the record, I have been using caliper rim brakes most of my life and I don't really have any experience with hydraulic disc brakes - and while modern rim brakes are indeed very good, I'd love more power and modulation.

^^ This is where discs shine, being able to feather the edge of braking.

For those of you who haven't, you need to try hydraulic discs.
Cable actuated discs are common in bike shops and if they are adjusted tight like some of you like your caliper brakes it will feel awful.
Hydros will feel "mushy" compared to a cable, but its great once you are used to it.

After a very ugly experience on a descent that I first went down today, I now really want a disc brake equipped road bike....So if anybody asks me if disc brakes should become legal on UCI road races,my final answer would be "Yes please!"
