TheSram Omnium Track 165mm 48T Chainset.The purists’ choice for street and track performance. The new Omnium track crankset is the first external bearing track crank in the world. 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.
