ceramic rotors for bicycles?

just wondering if these exist for bikes, you see them on high end cars so would a bicycle benefit from these? better stopping power? ligher?

hmm. I believe, possibly incorrectly, that ceramic brakes for cars only work at very very very high temperatures, so they may be unsuitable for MTBs.
However, there was a trend a few years ago in the days of rim brakes, of having ceramic coated rims, but I think that was aimed primarily at preventing your rims from wearing out.0 -
Yup, ceramic rotors only work properly once up to temperature, so no use for MTB's

ahh right, that's me learned cheers

F1 etc use carbon rotors, which only worth at high temperatures and wear very quickly , and can explode when they get too thin.
Some road cars use carbon/ceramic compounds which work OK when cool but better when hot. They last longer but considering it was a £20k option on the top porsches at one point I dont see them happening on (push)bikes not is there likelty a reason to bother.0 -
There are some carbon disc brakes for bikes. They were in a WMTB a few months back. But they were something like £800 each (But only weighed about 25g each).The first rule of cycling is - Tell everyone how great cycling is.

Rob, I think the carbon brakes used in racing are intended to solve the overheating problem - in that they can get much hotter before disintegrating. That allows a lighter weight of brake, and less convoluted cooling, which leads to higher general performance of the car. Again, I may be wrong.0

No your right. Therre to cope with the heat, repeted heavy from 200mph or so for 200 laps will do that:) They also dont work at low temps, neither do the tyres realy, whole car is setup to run at race speed (even the engine cooling).
I cant imagine coping with heat built up to that extent is needed on bikes - considering a lot of high performance cars cope fine with steel brakes - carbon/ceramic has only been 'standard' on a very few very high top end recent cars.0 -
the ceramic brakes work from about 700 deg C."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

did anyone see the Top Gear episode where the hamster drives an F1 car?
He was driving fairly fast, then they told him that the next step was to go MUCH faster.
If he only went a little bit faster, his tyres still wouldn't be warm enough, and his brakes would be too cold, so he'd crash :shock:
