    hi people. was cleaning my bike today and looked to the rear wheel and realised i have a bent disc rotor.

    is there anyway of straightening it without buying a new one??

    I usually use an adjustable spanner,a hammer or a pair of pliers and a rag.
    Put a rag on the warped bit then either use pliers or spanner and just twist it back into shape,or take it off the wheel,wrap in a rag,lay on a hard flat surface and hit the bent bit with a hammer

    Or instead of the ham fisted approach you could get a couple of these.

    It's similar to truing a wheel. First figure out what part of the rotor (wheel) is out of true and then bend it slightly in the opposite direction. I personally use a pair of CLEAN adjustable wrench and make small adjustments each time.
    Go on ahead, I'm gonna take a breather.

    It is not that tough to do

    The trouble with common sense is it is no longer common

    I usually just bend the out of true area back with an adjustable wrench (clean of dirt and oils). Not too hard though, and go in sections of the area.
