i just purchased a set of Shimano LX dual control shifters with hyrdraulic disc brakes. the kit did not come with rotors, so i planned to use the new kit with my existing rotors (Deore, tektro IO). i was at a bike shop yesterday and we were talking about this and he called shimano directly and they said i needed heat treated rotors.
what does that mean? are my current rotors heat treated? what difference does it make to braking performance?
wow man that sounds a little crazy, like rocket science. i have standard 6in rotors and they rock and have never even in extreme conditions given out on me or had brake loss due to heat. i know your setup, id consider just doing one rear hyd. brake for weight/racing purposes, maybe even not use front brakes at all or just use v brakes for front.
I dunno. But I think you can buy standard 6" shimano rotors for around 20 bucks or so.
