Ditch The Front Derailleur
These beautifully machined Wolf Tooth Components 110 BCD 4-Bolt Chainring For Shimano Cranks 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.
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.
Drop Stop-B works with all other 9, 10, 11, and 12-spd chains, including SRAM Flattop.
