Here is a good discussion about rim and disc brakes . http://www.bikeforums.net/road-cycling/1092227-braking-stopping-power-question.html
Apparently carbon makes for a poor brake surface for any brake, unless you are an F1 team and have the unlimited funds to make some discs that do work well in F1 cars. The rims the pros use today are aluminum based and carbon fused on the exterior to all but the braking surface. So you get lighter rims than alloy alone and that still have an alloy braking surface. While the bike industry would love for pros to adopt their brakes, many have tried them but prefer rim brakes. When it comes to riders safety they should always be the ones making the call. So both brakes have their place for certain riders and conditions. For many though the idea of adding signifigant weight to the bike trumps the endless argument of better/worse. Yes, for them it is signifigant. And then there are still some safety concerns of the roters since they are so sharp and the possiblility of a deep cut, different than a chainring. Aa for the perceived power and race strategy, riding a bike is really an art. It's not just what you ride but how you ride it, your intuition of how and when and why to take corners let alone everything else about it. Each is unique, Such is life ! Bravo ! Winning a sprint has nothing to do with brakes of course, and what you see on TV of close-ups of Kittels discs makes for good advertising and all, as does the whole race. But discs are pereived as "new and hot", look, "our hero Marcel rides discs, buy some". Human see human copy .... that's the theory at least.... ahahahahahaa ! -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
