    Bent crank chainrings?

    I think i may have bent my chainrings, but not sure if they are bent or if its normal for them to have a little side to side wobble it aid is shifting?
    Or are they supost to be totaly true?

    BTW they are TruVative Firex cranks

    Thanks!

    When they are made they are perfectly true.....so if they wobble at all they are bent. They can be bent to a certain point though before your shifting is ruined / your chain falls off constantly.

    it stays on and shifts, but it now rubs a little one the derailer cage thats what i noticed first. so maybe ill try bending it back if i can.

    Thanks!

    be very careful when bending it back. Take your time.

    weird, it seams only the middle ring is slighty bent. only about 1/16 tho... just enough to make it rub.
