Warp 9 Rawrr / Altis Sigma Sprocket

A rear sprocket machined from 7075-T6 aluminum for the Rawrr Mantis and the Altis Sigma, cut in the original 428 chain pitch. Six tooth counts are listed: 40, 42, 44, 48, 54 and 58.

Aluminum keeps weight off the outside of the wheel, where it costs the most in both acceleration and suspension response, at the cost of wearing faster than steel. Black anodizing is offered across the range and red on the 48 tooth. Extra chain links are not included, so a large jump up in tooth count may also need a longer chain. Check the front sprocket for hooked teeth while the rear is off.
