Setup, Compatibility & Care
This bottom bracket is specifically precision-engineered for Trek BB90 and BB95 frame shells and is intended for use with 24mm spindle cranksets (such as Shimano Hollowtech II).
- Preparation: Ensure the frame shell is clean, free of debris, and lightly greased according to frame manufacturer specifications.
- Installation: Insert the two sides of the Ninja bracket into the frame shell. Use a designated bottom bracket tool to thread the two halves together. The mechanical advantage of the threading ensures the unit is pulled perfectly square into the frame.
- Tightening: Tighten to the recommended torque settings to ensure the 'Fusion' locking mechanism is fully engaged.
- Maintenance: While the unit is highly durable, check for external contamination periodically and wipe the crankset spindle area during drivetrain cleaning to prevent grit from entering the bearing seals.
