I asked in the Road forum but got dismissed by the zero-body-fat crowd.
what I want to know is the best braking plan for hill repeats. I'm a ~270 clyde training on a hill a mile or two up and with some 15% sections.
when I do this on my road bike with rim brakes, the rims are incredibly hot once I get back to the bottom of the hill. this seems dangerous, though I guess I could just tear through pads if I'm not doing great harm to the rims.
would disc brakes be better though? They are available on a lot of road-ish bikes.
Drum brakes might seem ideal though they have limited availability. Also, I did a 2-mile descent with a front drum and it sure squealed down much of the descent.
