Wolf Tooth 110 BCD Shimano Asymmetric 4-Bolt Chainring

Wolf Tooth was first to market with cyclocross 1x specific chainrings because they saw cyclocross as the perfect use for their 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.

Drop-Stop B

Tooth shape is nearly identical to Drop-Stop A, but has narrower teeth. Valley between teeth is deeper to accommodate larger rollers on Flattop chain. Outside faces of narrow and wide teeth touch chain to guide alignment.

Features:

• 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
