Looks like one of the rotors on my bike is warped. The original specs for the 2010 Marin Alpine Trail 29er says the brakes use 6" rotors. Though the math doesn't add up exactly, some sites claim you can use 160mm rotors to replace 6" rotors. As someone who's new to wrenching on bikes and the compatibility of different parts, I'd like to make sure I don't buy the wrong size. Any info is greatly appreciated.
