No matter your power source, electric, gas, or otherwise, our chainring adapter will allow you to safely and reliably put the power to the wheel.  It mounts on a standard 6-bolt disc brake flange, and accepts 130mm BCD chainrings from 42T and up.  

It's CNC machined out of 6061 aluminum round bar, and clear anodized for a mellow glow.  It also has a pocket machined for a standard 1/2" Neo magnet if you're looking for a clean way to eliminate a spoke-mounted speed pickup.

Adapter only, hardware, chainring, and wheel not included.
