Aerodynamic 55T chainring for time trials & triathlon.

The FSA Aero TT chainring with 54 teeth was specifically developed for aerodynamic road bike, time trial, and triathlon setups. Its closed aero design reduces air turbulence and ensures optimized performance at high speeds.

With a 130 mm bolt circle diameter (BCD) and 5-arm mounting, the chainring is compatible with corresponding road bike cranks. Designed for 2x11-speed drivetrains, it provides precise power transfer in competition use. This outer chainring is ideal for combining with a 42-tooth inner chainring.
