    What would cause a rear Avid disc to warp? Is it something that happens often?

    One possible cause could be how you use the brakes. When you apply the brake it builds up heat both in the disc and the pads. If after stopping you hold the brake, the disc area under the pads cools at a different rate than the rest of the disc. The different rate of cooling can cause the disc to warp. The best way to avoid it is to release the brake and move the bike a bit so that the area can cool.

    dude, you probably just hit it on a rock or stump or something. It happens all the time. You can try to flatten it by putting it between to flat pieces of something and parking a car on it or something like that

    name of the game my friend. my wife just killed two rotors by throwing sh!t on top my spare set of wheels. i bend disc's atleast once every other month. yuo can tag rocks, logs, trees, small furry animals, you name it. a good long handle adj. wrench can bend a disc flat again.

    Ditto on the crescent wrench. If it is not bent to bad, you can get it close.

    who uses rear brakes? the wrench trick works pretty good. you might have to adjust the lever out a little to prevent rubbing. what you lose in friction you gain in momemtum.
