104 BCD Chainrings


The 104 BCD chainring was Wolf Tooth’s first product ever and it is the most common bolt pattern.  Because it is so commonly used, we offer a full gamut of colors!


  • These rings fit any 104 BCD crankset, and here are instructions on how to measure your BCD.  
  • Notes for those the plan to run a 32t chainring on a 2x Shimano crankset (XT, SLX, or Deore).
  • 30t x 104 ring is the only Quarq powermeter compatible 30t ring available!
  • For 1x9, 1x10, or 1x11 drivetrains
    • Compatible with all 10 and 11 speed chains.  
    • If using a 9 speed drivetrain use a 10 speed chain (shifts and works well on a 9 speed drivetrain and fits the ring tighter for better chain retention).


Complementing products:

64 BCD ring if you need something smaller than a 30t - will mount in your “granny gear” postion.
