Bottom Bracket FSA MegaExo 9050 MTB BSA 68/73

The FSA MegaExo 9050 MTB bottom bracket is a durable solution designed for mountain bikes using FSA SL-K cranksets with the MegaExo system. It fits BSA threaded frames with 68 or 73 mm bottom bracket shell width and is built for demanding off-road use.

The BB-9050 features oversized cartridge bearings housed in forged and CNC-machined external cups. This design ensures high stiffness, smooth rotation and long service life.

To protect the bearings from water and dirt, the bottom bracket uses an internal alloy center sleeve with double O-ring seals. It is designed for 24 mm hollow axles. FSA No Pinch Bolt cranksets use a threaded spindle, allowing the left crank arm to be mounted directly.
