SL-K Light 2x Crankset

What Our Gearhead® Experts Are Saying:

"I’ve ridden this crank on both a crit bike and a gran fondo build. The power transfer is snappy and direct, and even under hard sprints, it doesn’t flex. I especially like how light the arms are without compromising stiffness—it’s a serious value for a race crank."

The SL-K Light 2x Crankset is a proven choice for riders seeking lightweight performance and reliable power transfer on the road. Constructed with unidirectional carbon fiber and an internal alloy spine, the hollow arms strike the right balance of stiffness and weight savings for competitive use.

Featuring CNC-machined AL7075 chainrings and alloy chainring bolts, this crankset ensures high-precision shifting and long-term durability. It’s optimized for road racing, endurance rides, and fast training efforts. The 386EVO spindle enhances stiffness at the bottom bracket and is compatible with a range of BB standards via adaptors.

A clean, modern look pairs well with its road-focused geometry, while its solid construction ensures efficient energy transfer across a range of road conditions and bike platforms.
