Description
Specifications

Upgrade your cycling performance with the Full Speed Ahead SL-K 2x Modular Carbon Crankset - the perfect blend of lightweight engineering, cutting-edge technology, and durable materials designed for professional racers and serious enthusiasts alike. Featuring a 170mm crank arm length, this high-performance crankset is optimized for Shimano HG+ 12-speed systems, offering seamless compatibility and precision shifting.

Materials & Construction:

Crafted with FSA's proprietary Hollow Technology, the SL-K's ultra-light, hollow carbon crank arms deliver exceptional stiffness and strength while maintaining a low weight of just 650 grams. The sleek, durable UD carbon finish not only enhances its aesthetic appeal but also ensures resilience under demanding riding conditions. The premium 30mm CNC-machined 7050 BB386EVO spindle provides reliable power transfer and durability.

Performance & Engineering:

Designed for superior efficiency, the SL-K crankset features a 52/36T double chainring setup with cold-forged, CNC-machined FSA MegaTorque chainrings. These are engineered with advanced tooth profiles for optimal chain contact, reduced chain drop, and smooth, reliable shifting across all gears. The updated derailment angle on the non-contact side improves gear change responsiveness, ensuring quick and precise performance even under high loads.

Components & Technology:

The modular design includes a direct mount outer chainring and a 90 BCD inner chainring, providing flexibility for various riding styles, from road racing to gravel adventures. Compatibility spans 130mm and 135/142mm road disc hubs with chainlines optimized for 44mm, fitting hub spacing from 415mm chainstays and beyond. The spindle interface, 386 EVO, ensures compatibility with a wide range of modern bottom brackets.

Style & Use Case:

With its sleek black finish and carbon aesthetic, the SL-K is both visually striking and versatile. Ideal for road cyclists seeking high-performance gear, gravel adventurers requiring durability and weight savings, or riders looking for a premium carbon crankset that elevates their bike's look and feel.

Innovative & Differentiating Features:

- FSA Hollow Technology for ultra-light, stiff crank arms

- MegaTorque chainring technology for enhanced chain retention and shifting performance

- Modular 2x design for customizable gear options
