Details

Available for Shimano compatible mountain bike cranksets these CNC chainrings are sculptured in a way to enable significant weight reduction and shifting performance that is second to none. In order to be long-lasting, all rings are first CNC'd from Ergal 7075T6, then hard anodized, and finally machined on both chain sides.

Because of Extralite's unique pin and ramp system they do not recommend mixing and matching their chainrings with other brands for the best shifting performance.
