Designed for racing, and for those looking to optimize each detail in pursuit of speed, Wolf Tooth Elliptical Aero Chainrings are strong, lightweight, and profiled to mate perfectly with your crankset for a clean, integrated look. Taking advantage of 1x drivetrain systems and wider-range rear cassettes, Aero Chainrings provide similar overall range to standard 2x drivetrain configurations. They feature Wolf Tooth’s patented Drop-Stop design for the best wear life, chain retention, and mud clearance. Drop-Stop ST is specifically for the Shimano 12-speed Hyperglide+ chain, which is used by GRX 800 12-speed. Wolf Tooth engineered their elliptical chainrings to provide smoother, more efficient pedal rotation. This equates to better traction because of steadier torque on the rear wheel. With a Wolf Tooth elliptical chainring, you can harness more of your strength in the Power Zone, while having easier pedaling in the Recovery Zone.
