I've just built up a Kona Kula Supreme frame with 2008 Reba Team's.
Whenever I pedal hard I get rub sound from both the front and back rotors against the pads, but not when I'm riding straight.
I'm running XT centrelock disc brakes with a 180mm XTR rotor upfront and a 160mm XT rotor at the back with the appropriate mount adaptors.
Could this be fork flex or bad brake setup or just a symptom of being 12.5 stone lanky git on a XC hardtail?
Your thoughts would be appreciated.
