I'm going to rent a light road bike for a mountain ride later this month, anyone have tips about downhill braking and heat dissipation? I haven't used rim brakes in a long time and certainly not on a significant descent.
Is there some rule of thumb for not blowing your tires or melting off your pads? Should I let out some air first? The descent I'm worried about is about 2000m, on youtube it seems like everyone charges down the whole way at full blast. I'd rather have discs but it seems like most of the rental places near the mountain are renting stuff with rim brakes.
