FSA 386 MegaEvo Bottom Bracket – English Threaded (BSA), 68mm

The FSA 386 MegaEvo Bottom Bracket is the clean, purpose-built solution for running BB386EVO cranksets on frames with standard English-threaded (BSA) bottom bracket shells. It bridges modern oversized crank technology with traditional threaded frames—without compromise.

Featuring gold anodized aluminum cups, this bottom bracket offers precise machining, excellent durability, and a premium finish that stands out during installation and service. Inside, steel cartridge bearings provide smooth rotation and long-term reliability under the higher loads associated with 30mm axles.

Designed specifically for carbon road 386EVO cranksets, the MegaEvo system ensures proper bearing alignment, stiffness, and efficient power transfer—while retaining the simplicity and serviceability of a threaded interface.

Why we stock it at Go Grava:
Because threaded frames paired with modern cranks deserve a bottom bracket that is quiet, durable, and engineered to do the job correctly.
