100% Precision CNC machined from 7075 aircraft grade aluminum alloy, you cannot buy a better sprocket. We removed every little bit of material we could to make these sprockets as light as possible, using a unique design to maximize the strength while giving them a very distinctive look.

The key to a long lasting sprocket is the fit where each of the chain rollers fit into the teeth of the sprocket. Unlike stamped or cut sprockets, our fully CNC machined design insures a perfect fit between the chain and the sprocket, as well as the highest quality finish.
