Repair kit Park Tool BBT-18 Bicycle bracket tool Universal 4.34 cm
The Park Tool BBT-18 is a heavy-duty, investment-cast tool designed for installing and removing specific bicycle bottom bracket cups and front chainring lockrings. With a 4.34 cm diameter interface, it fits Shimano® Octalink® right-side bottom bracket cups that have external notches, Bontrager® ISIS Drive™ bottom bracket cups, and front chainring lockrings used on Bosch® Gen 3 and Gen 4 e-bike systems as well as Specialized® Levo® Brose® e-bike systems.
Manufactured from investment-cast steel for durability and precise fit, the BBT-18 offers a universal interface that covers multiple standards, reducing the need for several separate tools. Its 4.34 cm diameter and compatible notch profile ensure secure engagement with the specified Shimano, Bontrager, Bosch and Specialized components, enabling controlled installation and removal.
Position the BBT-18 tool onto the matching bottom bracket cup or chainring lockring so the external notches engage the tool profile. Use an appropriate wrench or handle to turn the tool counterclockwise to remove or clockwise to install, observing the component manufacturer's torque and orientation specifications. Ensure the tool is fully seated before applying force to avoid slippage or damage to the part.
Use with a compatible wrench or Park Tool handle designed for 4.34 cm interface tools. Verify component compatibility before use and follow the bicycle or motor-assist system manufacturer's service instructions and torque values. Keep the tool clean and lightly oiled to prevent corrosion.
