Full Speed Ahead SL-K 2x Modular Carbon Crankset - 165mm For SRAM AXS 12-Speed 48/35t DM/90 BCD 30mm 386EVO Spindle BLK

Engineered with advanced materials and fully in-house manufacturing the SL-K combines durability innovation and style making it the ideal choice for both professional cyclists and passionate enthusiasts looking for the best equipment. At the heart of the SL-K Light Direct Mount lies FSA’s Hollow technology which creates ultra-light hollow carbon crank arms. This design offers the perfect balance of lightweight construction and exceptional stiffness ensuring top performance and long-term durability. The sleek UD carbon finish enhances its aesthetics making it a visually striking and technically superior choice for demanding cyclists. The revolutionary MEGATORQ technology from FSA redefines the standard for chainring performance ensuring an unmatched combination of chain retention smooth shifting and durability. This innovation is the result of meticulous design and collaboration with professional athletes tested in extreme conditions to meet the highest expectations. The advanced tooth profile design creates an optimized contact point between the chain and chainring reducing chain drops even under maximum load. The updated derailment angle on the non-contact side further enhances shifting efficiency allowing for faster more precise gear changes without compromising retention strength.
