Wolf Tooth Elliptical 110 BCD Chainring - 42t 110 BCD 5-Bolt Drop-Stop 10/11/12-Speed Eagle Flattop Compatible BLK

Wolf Tooth Elliptical 110 BCD Chainring - 42t 110 BCD 5-Bolt Drop-Stop 10/11/12-Speed Eagle and Flattop Compatible Black. Designed for 110 BCD Cranksets. The proprietary design has an ovality of 10% and a timing of 112 degrees after top dead center which provide the benefits of an oval ring without the traditional downsides of oval rings. This chainring features the patent pending asymmetrical Drop-Stop tooth design for the best in wear life mud clearance and chain retention.

The simplest way to explain the way these rings feel is having 2 teeth less in the weak part of your pedal stroke and 2 teeth more where you have the most power
