here are some other cons for dis
requires more spokes= more weight less aero
rims will have to be over built in order to cope with rim crack around the nipple= more weight
hubs will need to be disc ready= heavier
forks will need to be reinforced= more weight
my question is has naybody ridden a long descent with disc brakes on a roadbike or tandem. to my understanding trek made a city bike with drop bars, sti's, fenders, and disk brakes i believe the name was "portland" or something like that. i believe some tandems have had disc brakes as an option for a number of years.
More spokes or different spokes? Back in the day I ran 32 hole Mavic 231's on the MTB with ceramic brake track and v brakes. Now I run 28 hole X317 with discs.
Rims won't need braking surface = less weight
Calipers can be hidden by fork fairing making them more aerodynamic.
I guess there will always be those who are naysayers but the time saved on a wet descent in the Alps would more than make up for any tiny tiny weight compromise - if any existed. Hell even A Schleck might have won the Tour.
Personally I can't wait. Switching from the MTB to the road bike is like going back twenty years when it comes to braking performance. I've been thinking of going discs anyway and this way at least we will see some ultralight rims to make the most of the opportunities.
