The FSA BB90 Trek Madone Kit is designed specifically for cyclists riding Trek Madone frames equipped with a BB90 bottom bracket shell who need a reliable replacement for their 24mm alloy cranksets. This kit utilizes high-quality sealed cartridge bearings to ensure drivetrain smoothness and longevity. While it provides excellent performance, it is important to note that this specific kit is precision-engineered for the BB90 standard and is not compatible with alternative bottom bracket shell types or non-24mm crank spindles.

No, this specific FSA BB90 kit is only compatible with 24mm alloy crank spindles.
It is not recommended. Using a dedicated bearing press is essential to ensure the bearings are seated squarely and to prevent damage to the bike frame.
BB90 is a proprietary bottom bracket standard developed by Trek, where bearings are pressed directly into the carbon fiber frame shell.
Service intervals depend on riding conditions, but you should inspect them if you notice play, clicking sounds, or increased resistance when spinning the cranks.
The kit includes the replacement bearings necessary for the BB90 shell; however, you will need a BB90-specific bearing press tool for installation.
Remove the crankset, inspect the bearings for wear, and ensure the bottom bracket area is properly cleaned and lightly greased.
Verify that you are using a dedicated BB90 press tool and that the frame shell is free of debris or residual adhesive from previous bearings.
Installation of this kit requires a professional-grade bearing press designed for BB90 systems. Because the BB90 standard uses bearings pressed directly into the frame, extreme care must be taken during the removal of old bearings to avoid damaging the carbon shell. Ensure the bottom bracket area is clean and lightly greased before seating the new cartridges. Regarding compatibility, this kit is strictly for 24mm alloy cranks; attempting to use a 30mm spindle will cause damage. Periodically check for lateral movement in the crank arms to ensure the bearings remain seated correctly.
