Shimano TL-FC37 Bottom Bracket Tool

This tool is specifically engineered for Shimano's Ultegra SM-BBR60 and XT BB-MT800 bottom bracket cups. It is not a universal tool, so verify your component model before purchasing.

Yes, the TL-FC37 requires a standard 1/2-inch drive socket wrench or torque wrench. It does not have a built-in handle, so you will need to pair it with a tool you likely already have in your workshop.

The SM-BBR60 and BB-MT800 cups use a smaller diameter interface than traditional external bearing bottom brackets. This adapter provides the precise fit required to engage the splines without slipping or damaging the softer alloy cups.

Absolutely. Because it utilizes a standard 1/2-inch drive, it is perfectly suited for use with a torque wrench, which is highly recommended to ensure you tighten your bottom bracket cups to the manufacturer's exact specifications.

No, this tool is designed exclusively for the specific Shimano bottom bracket standards listed. It will not fit other brands or even other Shimano bottom bracket models that use different spline patterns.
