Insaneclimber said:No disc brakes do not give better stopping power, think about it a rim brake has the ability to lockup and skid the wheel, so how then do disc brakes improve tyre traction, they dont do they, disc brakes are more powerful but the governing factor here is tyre traction. and last time i tried my "you beauty" v brakes in wet muddy conditions they locked the wheel too? Disc brakes give better modulation ( for dummies that means better feel)
Please. Anyone who has done any kind of white knuckle descent with standard road bike rim brakes (Ultegra/DA as an example) in wet conditions will tell you that it's virtually impossible to lock the wheel.
Two weeks ago I raced in abysmal heavy rain conditions the descents were more than a little scary and after one short descent into a hard left, rider after rider was unable to wash enough speed off running it through the corner. I had the lever locked in as hard as it would go and the wheel was a very long way from locking.
I've done enough long technical off road descents on my mtb with Hayes HFX-9 Carbons though all kinds of **** conditions to know that in the wet they are an order of magnitude better than *any* rim brake I've ever used.
