I have always run 160mm rotors front and back. I am building up a new bike and have a 140mm rotor sitting around that I want to try on the back. I am pretty light and may not need the stopping power of a 160mm imo...
Question:The brake contact of the 140mm will sit lower, as the diameter is less than the 160mm was.....so...do I need to lower the caliper down somehow so that it grabs the disc at the same height/level as it did on the 160mm??
Edit: ALSO, the brake mount is inside the rear triangle (carbon 29er frame On One). Seems like a "direct mount" setup where and adapter is not an option??
PS. Avid hydros with aligator rotor fwiw...
