Warp 9 E-Moto Sprocket

Warp 9's core rear sprocket for e-moto bikes, offered in aluminum or stainless steel across a wide run of tooth counts. Aluminum saves rotating weight at the outside of the wheel, where weight costs the most; stainless steel lasts considerably longer before the teeth hook over.

Tooth counts run from 40 up to 64. Fewer teeth raise top speed and lose low-end pull, more teeth do the reverse, which is why riders often keep two on the shelf and swap by terrain. Seven anodized finishes are offered plus an unfinished option. Extra chain links are not included, so a large jump in tooth count may need a longer chain as well as the sprocket.
