    140mm rear disc rotor?

    I`d like to convert my cross bike to disc and have been reading some of the posts on "disc size". I understand that it is possible to run a 140mm disc on the rear. I Have two questions. Firstly, where can I pick up a 6 hole, IS 140mm rotor? And secondly, What cable aspired caliper brake would function the best (hassle free - with no adapter headaches) for this application?

    Thanks for helping out.

    Any 51mm IS-compatible 160mm front caliper will work in the rear with a 140mm rotor, no modifications necessary.

    140mm rotors are common and easily available through the usual sources, both online or locally.

    140s are indeed harder to find, at least compared to the 160s and up. I got 2 Formula 140s from Stans. Of course forget about paying anything less then retail. I also wonder since as of 04, all they're rr's are 160s now...that the 140s may start getting harder to find. I use a 140mm on 2 NRS builds and love it for epics to xc racing, at least here in the SE mtns of N Ga, NC, etc. With any common brake like Avids, Hayes, etc..just run the front IS mount(Cambria's got'm for both brands$12-ish) in the back(or buy 2 front systems, but your lines will be too short if your running prebleed hydros). I've run both these brands, as well as the Formula B4SLs and Pros, all with 160/140 setups. Just as strong for all intent and purposes, but it will glaze sooner, all things being equal otherwise. Modulation is easier if anything IMHO, especially with the Avids, which would be my choice hands down if it had to be cable. Have yet to have any probs with glazing FWIW, and that includes many 2000'+ Pisgah descents, with one 3200'+ drop called Heartbreak Ridge thrown in. Yes indeedy.
