Already challenging Campagnolo and Shimano's dominance on the Road scene, SRAM's new Truvativ Omnium Track Chainset is the first external bearing track crank in the world.

Designed for world-class track racing, but also at home as the ultimate fixieĀ¯ crankset, the Omnium features SRAM's strongest and stiffest alloy, 7050-T6.

The full 5mm thick 7075-T6 chainring was developed for use only with 1/2 x 1/8 chains.
