The SRAM Omnium is the crankset serious track and fixed-gear riders reach for when a stock forged crank stops keeping up with their legs. Machined from SRAM's stiffest 7050-T6 alloy and paired with an external-bearing GXP bottom bracket, it turns raw effort into forward motion with almost no flex — the kind of upgrade you feel the first time you jump out of the saddle. It's a proven velodrome-grade piece, and it's the part that makes a fast fixed-gear build feel finished.
Key Features
- Forged 7050-T6 aluminum arms — SRAM's strongest, stiffest alloy — for near-zero flex under a hard sprint
- GXP external-bearing bottom bracket included: 24mm CroMoly spindle integrated to the drive-side arm, running on 4 sealed outboard cartridge bearings for stiffness and easy service
- 48T, 144 BCD chainring in 5mm-thick 7075-T6 — the industry-standard track bolt pattern, so you can swap rings to dial in your gear ratio
- Purpose-built for 1/2 x 1/8 track chains (not compatible with derailleur / 3/32 chains)
- A genuine race-pedigree upgrade over stock single-speed cranksets
