Description
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
- 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.
