Today i was riding with my brand new renthal chain(second ride) and it just snapped. The shop i bought it from said it is way over kill for my blaster and would last forever, guess not. So once i wheeled it back home i saw that by back sprocket was warped about .5 cm i asume this is from when the chain broke. The teeth are good so can i reuse this sprocket or will it cause acessive wear? Thanks
