Designed for racing, and for those looking to optimize each detail in pursuit of speed, Wolf Tooth 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 for Shimano Dura-Ace R9200 cranks are available in sizes 46T to 50T to provide similar overall range to standard 2x drivetrain configurations. They feature our patented Drop-Stop® ST tooth profile optimized for the Shimano 12-speed Hyperglide+ chain for the best wear life, chain retention, and mud clearance.

Recommendations

If you plan to ride in very muddy conditions, we recommend a chain guide or chain keeper in addition to a clutch-type rear derailleur. Without these precautions, you may experience chain drops and/or chain suck.
