SL-K Light 2x Crankset

What Our Gearhead® Experts Are Saying:

"I run the SL-K Light 2x on my endurance road build and it’s been rock solid. It’s stiff when I’m sprinting, but still feels light underfoot on long climbs. The carbon arms keep weight down, and it spins super smooth with my 386EVO bottom bracket. Just a clean, high-performance setup."

We trust the FSA SL-K Light 2x Crankset when every gram and watt counts. Built with hollow carbon arms and CNC-machined chainrings, this crankset hits the sweet spot between stiffness and lightweight performance. Whether we're lining up for a crit or chasing PRs on long climbs, it delivers precise power transfer and lasting durability.

The unidirectional carbon composite arms are reinforced with an internal alloy spine to reduce flex under pressure, while AL7075 CNC chainrings ensure crisp shifting. Its 386EVO compatibility means broad frame support, and with clean looks and a road-tuned Q-factor, it's a go-to crankset for efficient, fast riding.
