[quote=molgrips ]No-one goes on about V brakes being better than discs on MTBs when you're slithering down a muddy trail, so why would calipers be better than discs on smooth clean tarmac?
Cheese, chalk, strawmen.

Well, this seems to be saying that:

Btw, I'm amazed at how many pro peloton racers are concerned at the performance of the BB7s on their winter commuters. 😆

Ramsey Neil » when you are sat in the peloton there is going to be no difference at all .
Races aren't won and lost sat in the peleton.
Depends how you look at it Mark Cavendish has won plenty of races and I would suggest that all of his Professional wins have been when he's been sat in the peloton from the start to less than 1KM from the finish .
Just because Discs will be legal to use doesnt mean that they will all be using them for every race.
I'd imagine for a TT ,team or individual that they would use whatevers most Aero ie.Hidden or Shrouded caliper brakes.
For a Soggy classic such as Flanders I'd imagine discs would be more favourable.
Electronic shifting as a example is readily available but you still find plenty of guys using regular analogue shifting, Cancellara quite often still uses regular Dura-ace as opposed to DI2.

I'm surprised this drivel continues to fly around. Have you actually ridden (hydro) discs on the road? The key with braking isn't power - it's control. If you can feel and modulate the braking power then you can - if you are a good rider - brake to the limit of adhesion. And with really good brakes you can even feel when it's about to slide. In all respects discs are better than rim brakes in terms of performance, and therefore they can extract the most grip from the tyre. Just because you can jam on your rim brake and fly over the handlebar is irrelevant. It adds nothing to the debate.
+1 on reggie.
Anyway, by making discs legal, it'll mean they get developed to reduce/offset some of the downsides (weight/aero). That's a good thing even if the current models available aren't up to the job on performance alone (which I don't believe is the case but there will always be doubters).
No need to swoon sonny, have a swift gulp of oxygen... off you go.
If you can feel and modulate the braking power then you can - if you are a good rider - brake to the limit of adhesion.
If you don't have good modulation with good caliper brakes there's something wrong with your setup.
Away from road bike for a second, SLX brakes are usually held up as the best money/power ratio but they have very little modulation compared to a lot of other similarly priced brakes.
Has the effect of discs in a pile-up been covered? Is there a safety aspect to having a sharp frisby slicing it's way through the professional cyclist's soft flesh at every sprint finish for the first week of the TdF?
😆
Yes it has been , it was one of the reasons given for the non adoption of discs in the pro peleton a couple of years ago .
8 seconds was enough to win the tour de France in 1989 🙂
Lots of (Belgian pro) crossers are still using canti, watch this years world champs for example.
They will start to be used but it's not the biggest deal in the pro ranks at the moment

LeMond won the 1989 Tour because he used aerobars in the final Time Trial .
The point is that there will have to be a total adoption of disc brakes in the pro peloton because of neutral service needing to have a standard wheel , axle type and disc size .

Really? I've snipped the relevant bit, try re-reading...
wet or dry, with good calipers you can alredy easily overwhelm the available grip from a road tyre, and then youre sliding.
I've been running a pair of Avid Juicy Ultimates (were cheap at the time) since 2007 on my Roadrat with no problems with either corrosion or unwanted locking and it's mainly used as my winter road bike.

Yes, and in which bit of the race does he earn his money? I'm not sure you're reinforcing your point that much by pointing out that the bit where discs are irrelevant to performance is irrelevant to the result of the race.
I'm sure Cavendish will be an early adopter of discs, given how important braking is to his performance. 8s in 40km translates to 0.02s in 100m. At 60km/h you cover 33cm, or about half a wheel in 0.02s.

I don't know if there is a standard now? I assume everyone runs 11 speed these days but is campag compatible with sram/shimano? They already carry different sized bikes don't they?
Isn't cav wearing an aero helmet? I know he occasionally wears a skinsuit. He does care about aero as he wants to get to the line as fresh as possible. HE also has to survive the rest of the race such as mountains, chasing back on with a puncture, cross winds etc.
Road racing will be great now. Its been utter pants until now, but im worried my jaw will be harmed hitting the floor when i witness the awesome vision of race bikes with discs in action. The one day classics will be so much better. And i might even go and watch the tour live the year they're sanctioned the records book writers will be proper busy. I'm so excited.
interested in what you consider to be the main advantage of Vs if it wasn't power.though in reality ultimate braking power wasn't the main advantage
Ease of setup was nice, (less mud clearance was a disadvantage) but moar POWER! was the big thing for me.
I assume everyone runs 11 speed these days but is campag compatible with sram/shimano?
Yes. Even in the days when Campag/Shimano 8/9/10 speed weren't properly compatible riders just made do when necessary. That's obviously much harder with a disc that's rubbing...
It'll happen and it'll happen across the board - there are all sorts of ways of mitigating the issues (solid discs for example, maybe with a CF centre). And aero, etc will develop once they're being used and can deviate away from mtb designs (see Shimano's new disc 'standard'....)
Shut up will you about Discs on Roadies, you are disturbing me. 😕
