Wolf Tooth Oval 107 BCD Chainrings for SRAM

Wolf Tooth Oval 107 BCD Chainrings for SRAM Info

Wolf Tooth Oval 107 BCD Chainrings for SRAM are engineered for modern SRAM gravel and road cranksets that use the 107 BCD removable spider interface. Designed to pair seamlessly with SRAM AXS power meter spiders and standard removable 107 BCD spiders, these oval chainrings deliver smoother power transfer and secure chain retention for high-performance 1x drivetrains.

At the core is Wolf Tooth’s patented Drop-Stop® B wide/narrow tooth profile, optimized specifically for SRAM 12-speed Eagle and Flattop chains. The wide teeth maximize chain contact on the drive side to distribute load and extend wear life, while the narrow teeth allow mud and debris clearance to reduce friction and prevent chain drops. The oval profile further enhances pedaling efficiency by smoothing torque delivery through the stroke—particularly noticeable during sustained climbs and high-load efforts.

These chainrings are compatible with SRAM 107 BCD cranksets that feature removable spiders and are designed for front-of-spider mounting. Chainline is determined by the crank model, so riders should consult manufacturer specifications for exact drivetrain alignment.
