Full Speed Ahead Gamma Pro Chainring

This chainring is specifically designed for 11 and 12-speed 1x drivetrains. It is compatible only with FSA Gamma Pro and Alpha Drive 1x cranksets, so please verify your crank model before purchasing.

The alternating thick-and-thin tooth profile is engineered to lock the chain securely onto the ring. This design significantly improves chain retention, preventing drops even when you are riding over rough, technical terrain.

Yes, the 82mm Bolt Circle Diameter (BCD) is critical. You must ensure your crankset is compatible with this specific mounting pattern, as it will not fit standard 104mm or other common BCD crank spiders.

The heat-treated forged aluminum construction creates a denser, stronger material compared to standard stamped rings. This results in a much longer wear life, meaning you won't need to replace the ring as frequently, even with consistent, high-torque riding.

No, this is a dedicated single-ring (1x) chainring. It is optimized for the chainline and retention requirements of 1x systems and cannot be used in a setup with a front derailleur.
