Hey, I'm building up a new FR bike and I'm trying to get a feel for the right brake system to put on it. I'm a long time magura rim brake user and honestly I think a lot of the reviews I've read slamming brake systems is due to improper setup. Hydrualics can be a pain, but I'm not afraid to put the time in. I was hoping to get some input on Hayes 8" mags and the 4 pot XT's. I can't afford hope M4's, otherwise I'd probably get those. I dunno if anyone is lookin for new brakes, but cambria is clearing out HFX-9's and the previous XT for pretty good prices. Anyone have experience comparing these brakes? I'm looking for enough power to do light DH. Any thoughts would be great, thanks!
