Features:

• 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
• Features Wolf Tooth’s Drop-Stop tooth design for maximum chain retention
• Drop-Stop chainrings are designed for use with 1 x 9, 1 x 10, 1 x 11 and 1 x 12 drivetrains (Drop-Stop B)
• Drop-Stop B: works for all 9-12 speed chains including SRAM Flattop, SRAM Transmission, and Campagnolo. Not compatible with Shimano 12 speed or Campagnolo 13 Speed
• Shimano 12-speed chains require the use of Wolf Tooth’s Shimano 12-speed specific chainrings
• If using a 9-speed drivetrain, use a 10-speed chain, which will provide a tighter fit for better chain retention
• Not compatible with Shimano Dura-Ace 9000/Ultegra 6800, or Campy CX10/11
• Made from 7075-T6 aluminum for long life
• Use of a clutch-style rear derailleur is recommended
