Designed for world-class track racing, but also at home as the ultimate “fixie” crankset, the Omnium features our strongest and stiffest alloy, 7050-T6. The full 5mm thick 7075-T6 chainwheel was developed for use only with 1/2 x 1/8 chains. Reports from our test riders suggest that this is the stiffest crank they’ve ever ridden.
