Disc Brakes in 2016 for the Pros

Starting 1st Jan 2016.
This will be a game changer, and could be the beginning of the end for rim brakes on the pro ranks.

Looking forward to the cobbled classics.

Damn, now I have to stop saying that the UCI hasn't done even one good thing for cycling.

Well, not yet certain that this will be good or bad for pro racers, but effective roadable disc brakes have been around for a long time.

So the UCI has dragged their feet on this for easily 10-15 years. Sadly, the UCsillyI's main job apears to be preventing any technical improvements in this sport ...

What will be interesting is if during a mountain stage in the wet,, 1 team has discs and another does not,, how much of a performance difference the team with disc will gain.

Give them a bit more time. One of the refined skills of the UCI is reactionary last second rule changes. Only once all the teams and neutral service equipment is full in place will the UCI get its chance to change rotor diameter, axle spacing ect. and turn the thing into a total mess.

How about no difference?

Depends on if the team with rim brakes is smart enough to use wheels with aluminum braking surfaces or not...

Tom, do you think the pile-up crash from Stage 5 TdF would have happened if they´d all been on disc brakes, or decent rim brakes?

No way to know from that...but, that road looked pretty slick. Probably didn't matter what sort of brakes were used, would be my guess.

Calipers work just fine.

Pros will crash no matter what they ride. So will triathletes.

Disc brakes do have a place.

I saw this article this morning and it made me think of this thread...I thought I'd put this "nugget" here:
Quote:
Disc brakes, in their current incarnations, aren't aero. I'm sure we all guessed that. The magnitude of the difference is fairly significant.

"We've measured a 16% increase in wheel drag between a disc-braked wheelset and a standard wheelset", Jean-Paul told us. "We performed a direct back to back test of the Zipp 303FC in standard version and disc brake version, for our own competitor comparison purposes. That 16% is a constant offset in the performance curve across the entire cross wind angle range."

So there's work to be done there, but how much can actually be done? The extra drag essentially comes from three sources. The rotor itself adds drag, and because disc wheels need more spokes to cope with braking forces there's more drag there too. On top of that, a disc hub contains more material and needs to be built to withstand torque across the hub body, as the braking forces are on one side only. Because of that, the hub body is generally bigger and that increases drag as well.

What can be done about those three sources of extra drag? In reality, probably not a huge amount, and disc systems will likely continue to be at a disadvantage in terms of aerodynamics. So if you want to be as slippery as possible, it's rim brakes for the time being. And hide them, if you can.

When your riding wheel to wheel, the last thing anyone wants is a sudden decrease in speed; it would lead to VERY BAD outcomes. Disc brakes sure have their advantages, but I would imagine that there would be little benefit to prevent the severity of these kinds of peloton pile-ups. In fact, I could easily imagine that one 'twitchy' finger on disc brakes can make for some very scary group rides.

From my discussion with friends in the cycling industry, they all see this as simply another 'tech' push by the industry. Electronic shifting has been introduced, 11 speed has been brought out, so the next way to create market change is to push for the inclusion of discs on road bikes.
