Wolf Tooth Oval 104 BCD Chainrings

Wolf Tooth Oval 104 BCD Chainrings are engineered for riders who want smoother power delivery, excellent chain security, and broad drivetrain compatibility in a classic four-bolt format. Designed to fit any standard 104 BCD crankset, these oval rings are equally at home on trail, enduro, and e-MTB builds where durability and efficiency matter.

The oval profile features a carefully tuned 10% ovality with timing set at 112° after top dead center, helping reduce dead spots in the pedal stroke and maintain momentum through technical terrain and long climbs. Wolf Tooth’s patented wide/narrow tooth profile ensures dependable chain retention and effective mud shedding across a wide range of riding conditions.

Machined from high-strength 7075-T6 aluminum, the ring is compatible with 1x9 through 1x12 drivetrains, including SRAM Eagle, and is rated for e-bike use. Threaded construction allows the use of M8 chainring bolts without nuts, simplifying installation and improving long-term reliability.
