Specifications

Upgrade your cycling performance with the Full Speed Ahead SL-K 2x Modular Carbon Crankset - a perfect blend of lightweight engineering, advanced materials, and cutting-edge technology. Designed for serious road cyclists, gravel riders, and mountain biking enthusiasts, this 175mm crankset offers stellar efficiency, durability, and style for 12-speed Shimano HG+ drivetrains.

Materials & Construction:

Crafted from fully in-house manufactured, Hollow Technology carbon fiber, the SL-K crank arms deliver exceptional stiffness while maintaining a feather-light profile. The ultra-light, hollow carbon design reduces weight to just 650 grams, ensuring quick acceleration and effortless climbing. The durable UD carbon finish not only enhances aesthetics but also offers superior resistance to scratches and environmental elements.

Performance & Engineering:

Engineered for maximum efficiency, the SL-K 2x crankset features a 50/40T chainring setup optimized for versatile road and gravel use. The cold-forged, CNC-machined 7075 aluminum chainrings equipped with FSA's MEGATORQ technology provide outstanding chain retention, smooth shifting, and long-term durability - even under demanding conditions. The updated derailment angle and optimized contact point between chain and chainring minimize chain drops and improve shift precision, ensuring a confident ride on any terrain.

Components & Technology:

Built for high-performance applications, this crankset boasts a 30mm CNC-machined BB386EVO spindle that guarantees reliable power transfer and is compatible with 130mm hubs and road disc hubs with chainstays under 415mm or over 415mm. The modular design streamlines customization and maintenance, allowing you to replace or upgrade chainrings easily for different riding styles.

Style & Use Case:

With its sleek black finish and minimalist aesthetic, the SL-K crankset complements any bike build, from sleek road racers to rugged gravel grinders. Its versatile design is suitable for both competitive racing and recreational riding, offering superior performance in a lightweight, visually striking package.

Innovative & Differentiating Features:

- Fully integrated in-house manufacturing and advanced carbon fiber core for unmatched strength-to-weight ratio

- Hollow Technology carbon arms for optimized stiffness and weight reduction

- FSA's proprietary MEGATORQ chainring system for superior chain retention and smooth shifting

- Direct mount outer chainring for precise gear changes

- Compatibility with Shimano 12-speed HG+ systems and various hub configurations for ultimate flexibility

Whether tackling steep climbs, sprinting on flat roads, or navigating technical gravel, this crankset delivers power, precision, and style in equal measure.
