104 BCD Chainrings

The 104 BCD chainring was Wolf Tooth’s first product ever and it is the most common bolt pattern on double and triple cranksets. Wolf Tooth’s patented Drop-Stop tooth design is the best available anywhere. We offer a full spectrum of colors too!

Compatibility:

• These rings fit any 104 BCD crankset, and here are instructions on how to measure your BCD.
• 30 tooth rings require chainring bolts that are 7-10mm long. All other sizes require single ring specific bolts that are ~6mm long.
• Notes for those the plan to run a 32t chainring on a 2x Shimano crankset (XT, SLX, or Deore).
• 30t x 104BCD ring is the only QUARQ power meter compatible 30t ring available!
• For 1x9, 1x10, ,1x11 and 1x12 drivetrains (including SRAM Eagle)
• Compatible with all 10, 11, and 12 speed chains (Including SRAM Eagle)
• 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).

QUARQ is a trademark of SRAM, LLC, registered in the U.S. and other countries.

Complementing products:

Chainring bolts that are optimized for 1x

• 104 x 30t - our 10mm bolts are optimized for mounting this ring and/or this ring with our perfectly sized and matching bashring.
• All other tooth sizes - recommend our 6mm bolts.
• If using a bashring you will need 8mm bolts (most stock bolts on 3x cranksets are 8mm)

Our 104 BCD bashrings are optimized for use with our 104 and 64 BCD rings
