FSA Comet Modular MegaExo Crankset – 170mm Carbon Road Bike Component

The FSA Comet Crankset delivers rugged performance and adaptability for mountain bikers seeking a reliable 1x drivetrain solution without breaking the bank. Engineered for trail riding and aggressive terrain, this aluminum crankset combines strength with sleek design to maximize your power transfer while keeping weight in check. Its forged AL6061 arms provide unwavering stiffness during sprints and descents, while strategically placed channeling on the rear reduces bulk without sacrificing durability. Designed with convenience in mind, the no-pinch bolt system on the left crankarm simplifies setup and enhances aesthetics—perfect for riders who prioritize both function and style.

Whether you’re tackling technical singletrack or bombing downhill sections, the Comet’s thick-thin tooth profile ensures smooth chain engagement even under heavy loads or rough conditions. Compatible with both standard 135/142mm and modern Boost 148/148mm MTB hubs, this crankset seamlessly integrates into a wide range of frames, offering flexibility for different builds. Its direct mount steel chainring (32T) pairs effortlessly with 11- or 12-speed drivetrains from leading brands like Shimano or SRAM, providing crisp shifts and reliable traction across varied riding styles.

The Comet’s modular design shines in its ability to adapt to evolving bike setups—ideal for riders upgrading to Boost spacing or experimenting with chainline adjustments. While it doesn’t include a bottom bracket (BB), its FSA MegaExo spindle interface ensures compatibility with high-quality aftermarket options for tailored performance. With a minimalist black finish and a pedal spindle size of 9/16″, this crankset blends effortlessly into clean builds while maintaining its focus on durability.
