Aerodynamic 55T chainring for time trials & triathlon.
The FSA Aero TT chainring with 54 teeth was specially developed for aerodynamic road bike, time trial and triathlon setups. The 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 offers precise power transmission in competition use. This outer chainring is ideal for combination with a 42-tooth inner chainring.
