Warp 9 Ultra Bee Sprocket Aluminum

The aluminum rear sprocket for the Surron Ultra Bee, machined from 7075-T6 and black anodized, cut for the original 520 chain. Aluminum keeps weight off the outside of the wheel, where it costs most in both acceleration and suspension response.

Ten tooth counts are listed: 40, 42, 44, 46, 50, 52, 54, 56, 58 and 60. Fewer teeth raises top speed and softens acceleration; more teeth does the reverse and helps on steep, technical ground. Extra chain links are not included, so a large jump upward may need a longer chain as well. Aluminum wears faster than steel, so check the teeth for hooking each time the chain is adjusted.
