Recommended Torque Specs
Below are our general recommendations for torque specs. Please note:
- For torque specs involving other parts, always verify the maximum torque specs from the respective PARTS manufacturer.
- Never exceed the lowest of the manufacturer-recommended and the OPEN-recommended maximum torque spec
- All bolts should be greased prior to assembly.
- Always use a torque wrench!!

Recommended Bottom Bracket Installation
When installing the bottom bracket into the BB shell, a compound can be used dependent on the materials and style of the bottom bracket:
Bottom bracket with PressFit composite cup
Bottom bracket with PressFit composite cup
Carbon assembly paste
Bottom bracket with PressFit alloy cup
Bottom bracket with PressFit alloy cup
Moly based non metallic Anti Seize Compound
For example Loctite 234227 (LOC51048) Moly Paste Anti-Seize Compound)
Thread-together cups (Endura Torqtite, Wheels Mfg Thread-together, Token Ninja, etc)
Thread-together cups (Endura Torqtite, Wheels Mfg Thread-together, Token Ninja, etc)
Carbon assembly paste on the cups
That touch the BB shell), grease on the threads (the sections that thread together)
