The Unior 1671.2/4 Cartridge Bottom Bracket Tool is designed for older Shimano XT and XTR cartridge bottom brackets that use an 8-tooth splined interface.

Correct 8-Tooth Engagement: Some older cartridge bottom brackets look similar to standard 20-tooth cups but need a different tool. This 8-tooth design gives proper engagement and helps prevent slipping during removal or installation.

Strong Steel Construction: Made from hardened chrome-plated steel, the tool is built for workshop durability and repeated use. It gives mechanics the strength needed for servicing older or tightly fitted bottom bracket units.

Ratchet And Wrench Compatible: The tool can be driven with a 1/2-inch ratchet and also includes wrench flats on the body. This gives mechanics flexible handling options depending on the service setup.

The Unior 1671.2/4 Cartridge Bottom Bracket Tool 8 Tooth is a practical choice for servicing compatible older Shimano XT, XTR and similar cartridge bottom brackets.

How to use

Seat Tool Fully: Insert the 1671.2/4 into the bottom bracket or lockring interface until all 8 splines engage fully.
Avoid Partial Grip: Do not apply force if the tool is not fully seated, as partial contact can damage the cup or lockring.
Choose Drive Tool: Use a 1/2” ratchet, fixed handle, adjustable wrench on the body, or torque wrench when required.
Check Thread Direction: Confirm the bottom bracket cup marking before applying force, especially on older or Italian-thread frames.
Apply Controlled Force: Turn steadily while keeping the tool square to prevent slipping or rounding the interface.
