, Comet HD Modular 1x ME, Crankset, Speed: 11/12, Spindle: 24mm, BCD: Direct Mount, 32, MegaExo, 175mm, Black, Boost
The FSA Comet HD Modular crankset pairs solid forged 6061 aluminum crank arms with a 24mm chromoly spindle and FSA MegaExo interface. Rear channeling on the arms trims excess material while maintaining stiffness, and a no-pinch bolt design on the left-hand arm simplifies installation. This 175mm, single-ring crankset suits riders building a focused mountain bike drivetrain.
A direct mount steel chainring with a convertible spider design lets the crankset adapt to different chainring and chainline setups, including compatibility with 135/142mm MTB hubs and 141/148mm Boost hubs. The thick-thin tooth profile improves chain retention, and the 1x setup works with 11- and 12-speed drivetrains using a standard 9/16-inch pedal thread; a bottom bracket is sold separately.
