Is 2018 the year proper race bikes with discs gain momentum?

Couldn’t help notice that Sagan chose the rim brake venge over the disc. Now these brakes are poorer than your classic design yet obviously preferable to the extra weight and poorer aero of disc...

Also Kittel on the rim brake Aeroad not the disc.

I think the momentum is in the non disc direction.

But I won’t count out the manufactures demanding the pros “adopt” as without this I cannot see it happening.

In what way are the rim brakes ‘poorer’?......... they just take longer to stop when in the wet, it’s just something you get used to or are used to......

"they just take longer to stop when in the wet"

Is the answer.

i can't think of any reason why a few meters of extra stopping distance would matter? Even for cyclists who aren't Pros, taking longer to stop or not being able to control your speed as accurately doesn't have any significant consequences.

i have watched plenty of pro racing where they have been descending in the rain. Riders will often unclip to drag their feet for additional braking. What's wrong with that? Good enough for the Pros, good enough for me.

They don't drag their feet to slow themselves down, in fact they don't drag their feet on the ground at all, its about being able to put a foot down easily if they slide out. I must mention that it tends to be the less capable decenders in the peloton who do this too.

What about the opposite problem - people who can't descent will end up hitting corners way too fast and braking late. Even if they don't go ass-over-tit themselves, they'll end up causing others to slam into the back of them. If you ride down a mountain outside of your abilities, you're gonna fall and disc brakes won't save you.
It's ALL about the bike.

Remember.

Brakes stop the wheels. Tyres stop the bike.

He meant poorer than normal rim brakes. No one prefers the power or feel of Venge "sort of V-brakes" to any of the popular caliper rim brakes. The point being the world champ chose to run the crappiest existing rim brakes over the best current discs.

P.S. I rode 70mi today and never more than breathed on my brake levers. For rides like that aero and weight matter but braking just doesn't matter at all. There are a lot of rides and races like that.

The reason the pros keep riding the rim brake version is wheel swap logistics, to us a flat tire means repairing it at the side of the road, to them it means swapping a new wheel in as quickly as possible and chasing back on. That wheel could come from their team car, neutral service or a team mates bike. The speed, ease and compatibility of that change all have an impact on their potential for a result in the race. If they felt the actual brake performance was a step up enough to give them a benefit in real terms vs ease of swaps etc. Then you can bet that they would be using them more often, as it is the performance benefit just isn’t there for the pro’s.
