Bottom Bracket, BSA Shell, For MegaExo 24mm Cranks, 68mm, BB-6200/Di2

This FSA bottom bracket fits a BSA-threaded 68mm shell and accepts 24mm-spindle MegaExo-style cranksets, including FSA's Gossamer, Gossamer Pro, Energy, and TriMax lines. External cartridge bearings sit in CNC-machined aluminum cups, and a Di2-compatible composite center sleeve keeps the routing clear for electronic drivetrains through the shell.

Double o-ring seals at each cup limit water and grit intrusion around the bearings, and an anodized finish resists corrosion over repeated wet rides. The threaded interface allows the crank's left arm to mount directly to the spindle. Riders replacing a worn MegaExo bottom bracket can install this as a like-for-like swap.
