FSA MegaExo Bottom Bracket

This bottom bracket is specifically designed for FSA MegaExo cranksets with either 19mm or 24mm spindles. You must verify your crank spindle diameter before purchasing, as it will not work with standard 30mm spindles.

Yes, the FSA MegaExo system is engineered to handle the demands of both road and mountain riding. Just ensure your frame's bottom bracket shell specifications match the BB86 standard listed.

You will need a standard external bottom bracket tool compatible with FSA MegaExo cups. These tools engage with the external notches on the alloy cups to allow for proper tightening to the manufacturer's torque specifications.

These units are designed as a complete system, meaning the bearings are pressed into the alloy cups. While technically possible to press out bearings, it is standard practice to replace the entire cupset when the bearings wear out to ensure the best fit and performance.

This specific model is built for the BB86 standard, which features an 86mm shell width and 41mm shell diameter. If your frame uses a threaded shell, this press-fit style bottom bracket will not be compatible.
