Just constant use. My avids havent done so yet but I wouldnt be surprised if they did.What would cause a rear Avid disc to warp? Is it something that happens often?
Ditto on the crescent wrench. If it is not bent to bad, you can get it close.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.
