Renthal's hard anodised rear chainwheels are specifically designed for road and road racing applications and add increased wear resistance.

They are CNC machined from the same 7075 T6 material as  the Renthal off-road chainwheels, yet feature the increased longevity from the hard anodising process.

Hard anodising is an integral surface coating which significantly increases the hardness and wear resistance of the chainwheel surface.

This sprocket has a 76mm centre and 100mm PCD (bolt - bolt centre) with 5x 10mm bolt holes, and will suit both OZ Racing and Marchesini wheels sprocket carriers. (please check your sprocket carrier for measurements)
