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

The Wolf Tooth Elliptical 110 BCD Chainring in black is a game-changer. Designed for 110 BCD cranksets, it features a 10% ovality and 112 degrees timing after top dead center. This unique design offers the advantages of an oval ring without the typical drawbacks. Its patent-pending asymmetrical Drop-Stop tooth design ensures long wear life, great mud clearance, and excellent chain retention. It's like having 2 fewer teeth in the weak part of your pedal stroke and 2 more in the power part. Compatible with 1x9, 1x10, 1x11, and 1x12 drivetrains and most 10 - 12 speed chains (except Shimano 12 - speed). For 9 - speed drivetrains, use a 10 - speed chain for better fit. Made from 7075 - T6 aluminum for durability. A clutch - style rear derailleur is recommended. Not compatible with Shimano Dura - Ace 9000/Ultegra 6800 or Campy CX10/11.

Using this chainring is straightforward. First, make sure your crankset has a 110 BCD. Install the chainring securely on the crankset. If you're using a 9 - speed drivetrain, it's best to use a 10 - speed chain for a tighter fit and better chain retention. Remember, this chainring is not compatible with Shimano Dura - Ace 9000/Ultegra 6800 or Campy CX10/11, and Shimano 12 - speed chains need a specific chainring from Wolf Tooth. When it comes to maintenance, regularly clean the chainring to remove mud and debris. This will help keep the Drop - Stop tooth design working effectively and ensure long - term chain retention. It's also a good idea to check the tightness of the bolts periodically. Using a clutch - style rear derailleur as recommended will further enhance the performance of this chainring.
