SUPPLIER WAREHOUSE (add 3-6 days delivery): IN STOCK

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.

- Fits 110 BCD Asymmetric 4-bolt Shimano cranks
- Drop-Stop technology. On Wolf Tooth’s patented wide/narrow chainring, the wide side of the tooth has maximum contact on the drive side which spreads the load and improves chainring life. The narrow side allows clearance for mud and debris which reduces friction.
- Alternating wide/narrow tooth pattern prevents chain derailment


- Fits 110 BCD asymmetric 4-bolt cranks
- 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.
- Wolf Tooth inventory of SH110 chainrings all have the notch cut to fit the R7000, R8000, & R9100. Note: The 36 tooth chainring can not be modified, it is not be compatible.
- 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.

Compatible with all 10-, 11-, and 12-speed chains except Shimano 12-speed chains
Shimano 12-speed chains require the use of our Shimano 12-speed specific chainrings
If using a 9-speed drivetrain use a 10-speed chain. It fits tighter for better chain retention
