How do you go faster by fitting better brakes
So, you have a steep techie section. How do you go down it?
With canti's you roll into it with the brakes on and brake all the way down, suffering arm pump as you go.
With discs you have much more power and modulation. You apply a dab here and there quickly scrubbing off speed as and when you need it. They also inspire more confidence which helps you relax more. It all combines to getting down the hill faster.
In general terms, as Velo said you can also brake much later. You know those brakes are going to stop you much faster so you can also push harder off the brakes.
On a race car, effective brakes are worth more in terms of lap times that an engine with 60-70bhp more than an identical car. Back in my rallying days, I didn't have as much money as all the guys I was up against. I could not afford to spend £20,000 on the latest engine, but by spending £2,000 on the best brakes and suspension I was just as quick with a home built budget motor.
If proof were needed, look at a DH racer. His job is to get down the hill as fast as possible. Would he build up his bike with rim brakes?
