Made with the same top shelf aluminum alloy, to the same exacting fit and tolerance as the rest of our socket range, these sockets won't chew up your shiny new bottom bracket. 

Compatible with:

• Race Face Cinch 
  
• Sram DUB for 68/73mm shells
  
• Zipp Vuma Quad
  
• Rotor BSA 30
  
• Cane Creek Hellbender (mfg 2021 and later)

* If the bottom bracket has 12 notches and a 29 or 30 millimeter spindle and isn't made by Chris King, this is probably the right tool
