Cartridge bottom bracket wrench

material: Premium Flex carbon steel
• Bi-material ergonomic handle combining softness and firmness for extra comfort
• Consists of a wrench, item 1671,1, a bolt with nut, and a handle.
• The dual interface allows this tool to be used both for the SHIMANO standard on bottom brackets and for Shimano Octalink and Truvativ standards.
• How to use the tool:
• Advantage: when removing the bottom bracket, it is necessary to place the wrench on the bottom bracket cup nut. With the bolt, it is fixed to the axle. This prevents the wrench from slipping and damaging the bottom bracket cup nut. The job is made easier by the 350 mm handle length and the two-component ergonomic grip. The same procedure is used for installation.
