Wolf Tooth Shimano Chainring, 110 BCD Asymmetric Drop Stop B - black

Wolf Tooth was the first to bring cyclocross-specific 1x chainrings to the market because we saw cyclocross as the perfect application for our patent-pending  Drop-Stop® -  technology. These beautifully machined asymmetric 4-bolt chainrings with 110 BCD are optimized for your 1x Shimano CX/road/gravel drivetrain, whether you  ride Dura Ace 9000, Ultegra 6800, 105 5800, or Tiagra 4700  . They are also offset for the ideal 1x chainline.

• Fits asymmetric 4-bolt Shimano cranks with 110 BCD
• Drop-Stop technology. The patented wide/narrow chainring from Wolf Tooth has the wide side of the tooth with maximum contact on the drive side, distributing the load and improving the chainring's lifespan. The narrow side provides space for mud and dirt, reducing friction.
• The alternating wide/narrow tooth pattern prevents chain derailment
