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

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

Wolf Tooth 110 BCD Asymmetric 4-Bolt Chainrings for Shimano Cranks are purpose-built for riders converting their Shimano road, gravel, or cyclocross drivetrain to a clean and efficient 1x setup. Precision machined in Minnesota from premium 7075-T6 aluminum, this chainring delivers optimized chain retention, ideal chainline, and long-term durability for modern 1x performance builds.

Designed specifically for Shimano’s 110 BCD asymmetric 4-bolt crank standard, this chainring mounts in the big ring position and is offset inward to achieve a 47.5mm chainline—ideal for 1x drivetrains. The result is improved drivetrain alignment, reduced cross-chaining, and smoother overall performance whether you're racing cyclocross or building a streamlined gravel machine.

At the core is Wolf Tooth’s patented Drop-Stop® wide/narrow tooth profile. The wide teeth provide maximum chain contact on the drive side to distribute load and increase wear life, while the narrow teeth allow mud and debris clearance. The alternating tooth pattern actively reduces chain derailment—especially important in rough or muddy conditions.
