Wolf Tooth Elliptical Direct Mount Chainring - 30t SRAM Direct Mount Drop-Stop B For SRAM 3-Bolt Boost Cranksets 3mm Offset Black. Designed to fit SRAM cranksets with removable 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.

Elliptical rings provide smoother more efficient pedal rotation which means better traction

Shimano 12-speed chains require the use of Wolf Tooths 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

Made from 7075-T6 aluminum for long life
