  • Designed to fit SRAM cranksets with removeable spiders. Its proprietary design has an ovality of 10% and a timing of 112 degrees after top dead center which provide the beneifits of an oval ring such as greater rear wheel traction without the traditional downsides of oval rings.
    • Can also be used on long spindled BB30/PF30 cranksets
    • 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
    • Elliptical rings provide smoother, more efficient pedal rotation, which means better traction.
    • 49mm chainline for optimal rear shifting
    • Features Wolf Tooth's Drop-Stop tooth design for maximum chain retention
    • Made from 7075 Aluminum for long life
