I've watched the crash over and over, Kittel and his bike never come into contact with Doull.

Shimano XT hydraulic discs on my MTB are awesome, and have been since I bought it in 2008. If I often encountered the same conditions on my road bike then I'd want them on that, too - but I don't.

If I commuted all year in all weathers and wore out a pair of rims every year I'd want them on my commuter, but I don't even have one of those.

If I hadn't just bought - okay, a year ago - a new frameset to be my winter bike then I might want discs on that because I really hate the sound of grinding paste and the lanes round here get pretty stty.

But the last place I need them is on my next summer Sunday posh bike. And the last time I looked they were barred from most of the big Continental sportives - isn't that still the case?

I disagree. You don't "need" brake discs, in any situation, on a road bike. Rim brakes are perfectly adequate in any situation, I've descended 100s of km of wet/dry descents in the Alps, and you just ride accordingly to the conditions.

That's fine for recreational riding. But if disc brakes allow you to descend faster in the wet - because there is less need to adjust for conditions - then the pros will want them. Remember that the valid comparison is vs rim brakes on carbon rims. My view, having used both in the alps, is that discs have clear advantages in the wet.

That was the case but they're fine for the Etape du Tour at least. I'm happy that my ride for that event has discs - hopefully I won't need their undoubted benefits but I'll feel more confident knowing I have them.

I have just bought a disc equiped bike,why?
Simply because I wanted to and I had the choice.You can choose to stick with rim brakes if you like but progress is marching on.
If wheels don't have to withstand braking heat and force I wonder if wheel development will see some changes.

Perhaps if Doull was more concerned about his riding and sprinting technique than disc brakes, then perhaps he wouldn't end up on the floor in the first place...

Was mentioned somewhere yesterday (road.cc or cyclingweekly) that it's his left foot, Kittel was to his right and a rusty crash barrier was on the LHS of Doull.

How is it possibly the disc then? I can't see it being possible to hit the left foot with a rotor as it's protected by the other side of the bike?
This and only this.

You might not think they need discs but on an alpine descent in the wet I'm sure discs have their advantages. Consistent braking for starters.
I disagree. You don't "need" brake discs, in any situation, on a road bike. Rim brakes are perfectly adequate in any situation, I've descended 100s of km of wet/dry descents in the Alps, and you just ride accordingly to the conditions.

My first motorbike had drum brakes. I didn't die, just road to the equipment I had, but there is no way I would go back. Same with bicycles. I would rather have the extra ability of a disk and not need it than need it and not have it.

I am sticking with my comment- Pinarello, Cervelo, Colnago, Bianchi and the likes have not embraced discs like other manufacturers despite the model above.
How did his left foot get caught up with a disc which would have been next to his right foot? He ripped his foot on a barrier so why claim it was a disc? Lying is just what Team Sky need right now isn't it?
Colnago offer disc brake bikes and have done since the C59 in 2012.

Bianchi offer at least 4 disc models.

Pinarello as above and Cervelo are Canadian?

if disc brakes were the norm and somebody just came up with the idea for rim brakes it would probably be chosen over discs by some pros.

Why? Rim brakes allow for a lower aero drag system. Professional cycling success is tied to how fast you can go with limited power, race finishes are not decided by small percentage improvements in braking modulation.

yes If only Pinarello produced a high-end disc-braked frame that Team Sky could use. Something like the F8, but with discs:

Oh...rolleyes

You're an idiot. They all have disc models. Simple business model. Demographic want A, offer A. In this case, the majority of people want discs.


I won't, and you'll never catch me on a disc'd roadie. Not because someone may or may not have caught their foot on the disc. No, because discs are fking ugly.

You'll be lucky to find anyone who has bought a disc braked road bike and would go back to calipers, I certainly wouldn't. The control over braking is far superior.

Pros have traditionally opposed new technology, it took quite a while before they accepted cotterless chainsets over the old cotter pin steel cranks on the grounds they looked too weak. If it was good enough for my dad it's good enough for me unless I can find something that was good enough for my grandad, has often been the mantra.

I'm sure you missed the smiley off when suggesting some one is an idiot and then go on to say you choose a bike on looks rather than performance.

The disc brake is still reliant on the contract patch on the road though, which is the tyres. If you need help modulating brake power or whatever the marketing people have told you discs offer, then the very last place you should be cycling is an alpine descent in the rain...

It's not progress, it's something different. It offers an advantage in some situations like winter commuting but the pros, who are a lot better at bike handling than us, just don't need disc brakes.... look at Froome descending, he barely touched the brakes, just adopted a crazy position and held on for dear life, add others have said that stage want won because he had better braking capability compared to others...

This shows what it takes to cut a shoe with a disc brake.

I am an idiot? I didn't say they don't produce disc models did I? I said they have not embraced and pushed the technology as much as some of the other companies. Discs perform better and now wheels can be built without compromise (brake track). Carbon wheels become much more viable.
You can choose to dismiss disc brakes for whatever reason you want but doing it on style is a bit dumb. Take it you only run 9 speed 12-23 cassette as big cogs are ugly as sin or have you embraced progress and moved on to 11 speed 11-28?

If it is only something different,why are so many people getting their knickers in a twist.Usually you talk sense but not on this topic.It's about choice,use disc brakes or calipers,I don't care,it's your choice.

Discs do provide an advantage on big descents. Not everyone in the pro peloton is an insane bike handler nor are they gung ho. Some are clearly better than others at throwing themselves downhill. Discs allow greater modulation, less fade and more confidence in stopping, particularly in the dry. Anyone who suggests rim brakes are as good as discs simply haven't tried them downhill. I didn't like the idea of discs on road bikes at first but since trying them I am converted, whether they look good or not.

Front and rear suspension optimised for road courses would also offer handling and road holding advantages.

I wonder if we will see full suspension pro road race bikes soon?
