Re: Are Disc Brakes Faster? Disc Brakes Vs Rim Brakes | GCN Does Science [BMANX]
Not hard science, but certainly food for thought.

But some huge problems with this test:

The rim brakes are very significantly handicapped. Rim brakes on carbon rims are generally poor, and they are absolute sh*t on carbon rims in the wet. But rim brakes with optimal brake pads on AL rims are excellent, and they're pretty reasonable on AL rims in the wet (again, this is with the right rim brake pads; with bad pads this is not case).

It would really be interesting to see this test repeated with both systems optimized but with, say, a 215 lb rider in 95 deg temps and direct summer sun. I wonder how things would pan out then. Because disc brakes have some, uh, interesting (i.e., very scary) failure modes in high heat and high brake loads ...
