Description
Specifications

Upgrade your cycling performance with the Full Speed Ahead SL-K 2x Modular Carbon Crankset - a precision-engineered component designed for high-speed road and gravel riding. Crafted from advanced materials and manufactured entirely in-house, this 165mm crankset combines cutting-edge lightweight technology with superior durability, making it the perfect choice for both professional athletes and passionate cycling enthusiasts.

Built with FSA's innovative Hollow Technology, the SL-K's ultra-light, hollow carbon crank arms provide an optimal balance of stiffness and weight savings, enhancing power transfer and responsiveness on every ride. The sleek UD carbon finish not only boosts aesthetic appeal but also ensures long-lasting resistance to the rigors of demanding terrains.

Featuring FSA's renowned MEGATORQ technology, the chainrings deliver exceptional chain retention, smooth shifting, and remarkable durability. The cold-forged, CNC-machined 7075 aluminum chainrings with precision tooth profile design reduce chain drop risks, even under high load, while the advanced derailment angle on the non-contact side facilitates quicker, more precise gear changes. Compatible with Shimano HG+ 12-speed groups, this crankset offers seamless integration with modern drivetrain setups.

The 30mm CNC-machined BB386EVO spindle ensures reliability and stiffness, supporting efficient power transfer. With a 44mm chainline and a Q-factor of 174mm, the SL-K crankset is optimized for optimal clearance and efficiency on both road and gravel bikes, fitting 130H hubs and accommodating bikes with chainstays under 415mm or over 415mm.

Key Features:

- 53/39T double chainring setup with direct mount outer and 90 BCD inner chainrings designed for Shimano HG+ 12-speed systems

- Ultra-light, stiff carbon crank arms utilizing FSA's Hollow Technology for enhanced performance

- Precision cold-forged CNC aluminum chainrings with MEGATORQ technology for superior chain retention and smooth shifting
