Wolf Tooth Oval 110 BCD Asymmetric 4-Bolt Chainrings for Shimano Cranks

Wolf Tooth Oval 110 BCD Asymmetric 4-Bolt Chainrings for Shimano Cranks Info

The Wolf Tooth Oval 110 BCD Asymmetric 4-Bolt Chainrings for Shimano Cranks bring modern 1x performance to a wide range of Shimano road groups. Designed specifically for the asymmetric 110 BCD road standard, these oval chainrings deliver smoother power application, improved climbing traction, and exceptional chain retention thanks to Wolf Tooth’s patented Drop-Stop® tooth profile. Mounted in the big-ring position with an optimized inward offset, they create a precise 47.5 mm chainline ideal for 1x road, gravel, and all-road builds.

Compatible with popular cranksets—including Dura-Ace 9000, Ultegra 6800, 105 5800, Tiagra 4703/4700, Sora R3000/R3030, and Claris R2000/R2030—these chainrings allow riders to simplify their drivetrain without sacrificing reliability. For Dura-Ace 9100, Ultegra 8000, and 105 R7000 cranks, sizes 40T and larger can be used with a quick, minor modification to the crankarm profile. They are not compatible with the latest Dura-Ace R9200, Ultegra R8100, or 105 R7100 series.

The oval shape reduces dead spots in the pedal stroke, maintaining traction during steep climbs and enhancing overall efficiency. To complete the conversion, Wolf Tooth 6 mm chainring bolts are required, as stock 2x bolts do not seat correctly with a single-ring setup. The chainrings perform best when paired with a clutch-style rear derailleur, and riders using 9-speed drivetrains should run a 10-speed chain for tighter engagement.
