I was touring CES when I wandered over to the Intel/BMW Formula One Auto Team exhibition. The F1 team had a bunch of displays for people to touch and play with. One impressive display was the steel disc brake rotor for a normal production car…and the full carbon disc for the F1 car. Talk about a huge difference in weight.
I’m not a big fan of disc brakes, but I was wondering why carbon disc brakes are not being built for cycling. Is it cost? Service life?
