FSA Premium MegaExo Bottom Bracket

This bottom bracket is designed for frames with a standard BSA threaded shell width of 68mm. If your frame uses a different standard, such as PressFit or BB30, this component will not be compatible.

This bottom bracket is specifically engineered for the FSA MegaExo 24mm spindle standard. While it may physically fit other 24mm spindles, it is optimized for FSA cranksets and we recommend sticking to the manufacturer's intended pairing for the best performance and fit.

The CNC machining process ensures extremely tight tolerances, which means the bearings sit perfectly aligned within the shell. This precision reduces the likelihood of creaking and ensures a smoother, more efficient rotation compared to stamped or lower-quality alternatives.

While this component is intended for road use, its robust construction and high-quality bearings handle standard road conditions with ease. If you are riding in extreme mud or grit frequently, you may want to consider a sealed unit specifically marketed for cyclocross, but for light gravel, this will perform reliably.

Yes, you will need a standard external bottom bracket tool compatible with the FSA MegaExo interface. Ensure you have the correct wrench or socket to avoid damaging the cups during installation.
