Ultralight Alloy Road Rear Sprockets

Renthal® Ultralight™ Hard Anodised Rear Chainwheels are specifically designed for Street and road racing applications.

CNC machined from the same 7075 T6 material as our offroad chainwheels, with increased longevity from the hard anodising finish. Hard anodising is an integral surface coating which significantly increases the surface hardness and wear resistance of the rear sprocket.

Typically available in Ultralight or Race Conversion pitches and a variety of tooth sizes where applicable. Race conversion chainwheels are chosen by many factory teams across World Superbike and National Superbike paddocks. A performance upgrade for your street or trackday motorcycle.
