FSA SL-K Light Direct Mount Crankset: Advanced Performance
FSA has introduced the SL-K LIGHT Direct Mount crankset, a cutting-edge product designed to deliver top-level performance at an accessible price point.
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.
Performance and Innovation
The SL-K LIGHT Direct Mount embodies FSA’s commitment to delivering high-performance products. Every component is meticulously designed for optimal compatibility and efficiency. The innovative lockring system on the left crank arm allows precise micrometric adjustments, ensuring compatibility with a wide range of frames, even those with less precise tolerances.
This approach highlights FSA’s dedication to superior quality and functionality.
Hollow Carbon Crank Arms
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.
Perfect Harmony
The SL-K LIGHT Direct Mount crankset is designed as a cohesive system, where every component works in harmony to maximize power transfer.
The direct-mount chainrings are precision CNC-machined, while the 30 mm aluminum spindle ensures outstanding stiffness.
Together, these elements create a reliable, high-performance crankset that delivers consistent results on any ride.
Revolutionary Chainrings
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.
Lab tests have proven the superiority of MEGATORQ, with a 45% improvement in chain retention compared to previous designs and a 39% performance advantage over the closest competitor.
These results are achieved through precise engineering, including a finely tuned pitch and spacing between the teeth, ensuring maximum power transfer and reliability. Additionally, the MEGATORQ chainrings undergo rigorous in-house testing to simulate real-world scenarios.
A custom-built testing machine applies loads of up to 100 kg to replicate extreme conditions, ensuring these chainrings can handle up to 3780 watts of power and 62 Nm of torque, well beyond the industry standard.
Field-Tested Performances
The SL-K LIGHT Direct Mount crankset has undergone rigorous testing, both in the lab and on the field. Collaboration with professional teams like EF Education and Uno-X provided valuable feedback to fine-tune the design.
Lab tests show the crankset can withstand extreme loads of up to 3780 watts, ensuring reliable performance even in the most demanding conditions.
Technical Features
The SL-K LIGHT Direct Mount combines premium materials and meticulous engineering.
Its hollow carbon crank arms are paired with a 30 mm aluminum spindle and CNC-machined direct-mount chainrings.
Available in configurations such as 50/34T, 52/36T, 53/39T, and 54/40T, it supports Shimano/FSA 12-speed drivetrains.
