FSA SL-K Carbon Tandem Crankset: Precision Engineered for Dual-Rider Performance

Designed for tandem cyclists seeking unmatched power transfer and reliability, the FSA SL-K Carbon Tandem Crankset combines cutting-edge engineering with lightweight durability. Built around a 30mm carbon spindle and hollow UD carbon arms, this crankset delivers exceptional stiffness-to-weight ratio, ensuring every pedal stroke translates into forward momentum—perfect for long-distance rides or competitive tandem events.

Its 392 EVO spindle interface offers precise alignment and adjustability, accommodating various frame geometries. Whether tackling steep climbs or maintaining high speeds on flats, the SL-K’s tapered 9/16″ pedal threading ensures rock-solid stability under dual-rider power loads.
