FSA Energy Modular Crankset BB386EVO 170mm Crank Arms Upgrade

The Energy Modular BB386EVO Crankset is engineered to deliver elite performance across road cycling, gravel adventures, and rugged terrain. Its versatile design centers around the robust BB386 EVO 30mm spindle system, ensuring seamless compatibility with frames using various bottom bracket standards—making it an ideal upgrade for riders seeking flexibility without compromising power transfer.

Crafted from high-grade 7050-T6 aluminum alloy, these cold-forged hollow crank arms combine lightweight efficiency with unmatched durability. Paired with a precision-machined BB386EVO spindle and direct-mount outer chainring configuration (46/30T), this system offers crisp shifting and responsive pedaling under demanding conditions. The inner 90 BCD chainrings are forged from the same aerospace-grade material, while chromoly bolts provide secure fastening even on bumpy trails or high-speed descents. Designed for modern drivetrains, it’s fully compatible with Shimano and SRAM 10/11-speed setups, giving you reliable gear transitions whether you’re tackling steep climbs or maintaining pace on open roads.

Perfect for gravel grinders or all-day road rides, its 130mm chainline ensures optimal hub alignment and quieter operation on mixed-surface routes. At just 755 grams (170mm length), this double-chainring setup strikes an impressive balance between strength and weight—critical for endurance athletes or competitive cyclists prioritizing every gram saved. Unlike fixed-spindle systems that limit frame choices, Energy’s modular design lets you adapt to existing builds without extra costs or complexity.
