FSA

SL-K 2x 50/34t Modular Carbon Crankset - For Shimano HG+ 12

The FSA SL-K Light Direct Mount Crankset blends cutting-edge materials and in-house engineering to deliver lightweight strength, efficient power transfer, and refined style. At its core, FSA’s Hollow Technology creates ultra-light, hollow carbon crank arms that strike the ideal balance between stiffness and weight savings. Finished in sleek UD carbon, the SL-K Light is both visually striking and performance-driven.

Cold-forged, CNC-machined 7075 aluminum chainrings feature FSA’s MEGATORQ technology, engineered for superior chain retention, smooth shifting, and long-term durability. An updated derailment angle further improves shifting precision, minimizing chain drops while maintaining retention under heavy load. Paired with a CNC-machined 30mm BB386EVO spindle, this crankset is designed to meet the demands of professional cyclists and enthusiasts alike.
