FAQs
What types of bottom brackets does this wrench work with?
This wrench is designed for external bottom brackets from brands like Shimano (Hollowtech II), Campagnolo (Ultra-Torque and Power Torque), Race Face, FSA, SRAM, Truvativ, and Chris King, provided they have 16 external notches.
Can this wrench be used on disc brake rotors?
Yes, it is compatible with disc brake rotor locknuts that feature 16 external notches, specifically those used in CenterLock systems.
Does the crank arm need to be removed?
For some bottom bracket installations or removals, the crank arm may need to be removed to allow the wrench to fully engage with the bottom bracket cups.
What material is the wrench made of?
The wrench is made from premium flex plus carbon steel.
How do I clean and maintain the wrench?
Wipe the wrench clean with a dry cloth after use and store it in a dry environment. Avoid harsh chemicals that could damage the chrome finish.
Is this wrench suitable for press-fit bottom brackets?
No, this wrench is specifically designed for external cup-style bottom brackets and will not work with press-fit (PF) or internal bearing bottom brackets.
What does the '16 Notch' refer to?
The '16 Notch' refers to the number of external teeth or splines on the wrench head that engage with the corresponding notches on the external bottom bracket cups or disc rotor locknuts.
Troubleshooting
Wrench slips on the bottom bracket cup.
Ensure the crank arm is removed if it's obstructing full engagement. Verify that the bottom bracket cup has 16 external notches and is the correct type for this wrench. Apply firm, even pressure.
Difficulty removing a tight bottom bracket.
Ensure the correct leverage is applied. You may need to use a breaker bar or extension on the wrench handle. Apply a penetrating lubricant to the bottom bracket threads and allow it to sit before attempting removal again.
Wrench does not fit a specific component.
Confirm that the component is compatible (e.g., Shimano Hollowtech II, Centerlock rotor nut with 16 notches). This wrench is designed for external cup bottom brackets and specific rotor nuts, not internal or press-fit types.
