Cartridge Bottom Bracket Wrench

Description

The Unior Cartridge Bottom Bracket Wrench is a professional-quality tool designed for the precise installation and removal of cartridge bottom brackets. Made from premium Flex Plus carbon steel and equipped with a heavy-duty ergonomic double-component handle, it delivers strength, comfort, and control during use.

Thanks to its double-threaded screw system, this wrench is compatible with both Shimano standard bottom brackets and Shimano Octalink/Truvativ types. The additional screw allows the wrench to be threaded securely into the axle, preventing slippage and protecting the bottom bracket from damage during service.

With a 350 mm long handle and removable design, it offers excellent leverage and convenient storage — ideal for both professional workshops and home mechanics.
