Is anyone running a larger rotor than 6" on a MX pro. I have an 04 and am looking for more braking power from my Hayes Mags. I ride mostly aggressive XC and just want to never have to use more than one finger to get the power I want. I know Mar says they don't recommend it since they only have 30mm lowers but my thought is either way I am putting the same force into the wheel with either setup, I am just putting two fingers on with the 6 to clamp down. I read about fork flex and possible accelerated bushing wear but don't buy totally into it. Does anyone have experience with this combo and have they had any problems?
