FSA SL-K Carbon BB30 XX1 Crankset

The advent of super-wide range 11-speed cassettes on mountain bikes has made a single-chainring setup a real option for many riders. The SL-K Compact Single uses FSA's 386 three-armed spider that delivers huge stiffness.

The crank arms are unidirectional carbon fibre with an alloy spine inside to boost strength with a minimal weight penalty. The chainring is CNC machined from high-strength 7075 aluminium. The rings are optimised for use with 11spd transmissions and are designed for maximum chain retention. It also features a forged 7075 BB30 spindle.


  • UD carbon composite arms with alloy spine
  • Optimised for new 1X11-speed MTB systems
  • Finish: UD carbon finish
  • BCD: 86mm
  • Crank Weight: 666g
