110 BCD Asymmetric 4-Bolt for Shimano Cranks

Wolf Tooth was first to market with Cyclocross 1x specific chainrings because we saw Cyclocross as the perfect use for our patent pending Drop-Stop® technology. These beautifully machined 110 BCD Asymmetric 4-bolt chainrings are optimized for your 1x Shimano CX/ Road/ Gravel drivetrain whether you run Dura Ace 9000, Ultegra 6800, 105 5800, or Tiagra 4700. They are also offset for the ideal 1x chainline.

Compatibility:

• These rings are for use with 110 BCD Asymmetric 4-bolt cranks. Here is how to measure your BCD.
• Compatible with Dura Ace 9000, Ultegra 6800, 105 5800, Tiagra 4703, and Tiagra 4700
• Sizes 38T and larger are compatible with Dura Ace 9100, Ultegra 8000 and 105 R7000 but a slight modification is required due to a change in the crank arm profile. The 36T chainring will not work for this modification. Click here to review the process for the modification, which takes about 5 minutes to perform.
• Confirmed modification fit with Dura Ace 9100 Power Meter in size 42t or larger
• Mounts in the big ring position of the cranks but is offset inward for perfect chainline.
• The stock 2x bolts will not work. You will need our 6mm bolts which are optimized for single ring mounting.
• For 1x9, 1x10, 1x11 and 1x12 drivetrains including SRAM Eagle (TM)
  • Compatible with all 10, 11, and 12 speed chains including SRAM Eagle (TM)
  • 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).
