Compatibility

• These rings are for use with Shimano 110 BCD Asymmetric 4-bolt cranks.
• Compatible with Dura Ace 9000, Ultegra 6800, 105 5800, Tiagra 4703 or 4700, Sora R3000 or R3030, and Claris R2000 or R2030 cranks.
• Sizes 40T 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 38T chainring will not work for this modification.  Click here to review the process for the modification, which takes about 5 minutes to perform.
• NOT compatible with Dura-Ace R9200, Ultegra R8100, and 105 R7100 Cranks
• 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.
• Wolf Tooth’s patented Drop-Stop® wide/narrow tooth profile for the ultimate chain retention and mud shedding ability
• 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).
• Chainline - 47.5mm
  

Recommendations

• If you plan to ride in very muddy conditions, we recommend a chainguide or chainkeeper in addition to a clutch-type rear derailleur! Without these precautions, you may experience chaindrops and/or chainsuck.
• Recommend the use of a clutch style rear derailleur for the best chain security.
