Wolf Tooth 96 mm BCD Chainrings for Shimano XTR M9000 and M9020

Wolf Tooth 96 mm BCD Chainrings for Shimano XTR M9000 and M9020 Info

The Wolf Tooth 96 mm BCD Chainrings for Shimano XTR M9000 and M9020 deliver the trusted chain retention and drivetrain refinement that riders have come to expect from Wolf Tooth’s precision-machined components. Designed specifically for Shimano’s XTR M9000 and M9020 cranksets, this chainring brings the brand’s signature Drop-Stop technology into a platform optimized for modern 1x performance. It’s an upgrade chosen by riders who demand clean power transfer, dependable retention, and the kind of long-term durability that makes a real difference out on the trail.

Machined from premium 7075-T6 aluminum, the chainring features an asymmetrical 96 mm BCD with integrated threaded standoffs—ensuring a dialed chainline whether you’re running 30–36T. The Drop-Stop tooth profile balances efficiency and security by using alternating wide/narrow teeth that clear mud, minimize friction, and keep the chain locked in place even under heavy load or riding through rough terrain. This detail-oriented approach is why Wolf Tooth rings remain a benchmark across XC, trail, and endurance mountain riding.

The 96 mm BCD ring is compatible with 1x9 through 1x12 systems, including SRAM Eagle, making it a versatile option for riders modernizing older drivetrains or fine-tuning current setups. Shimano XTR hardware threads cleanly into the chainring’s standoffs from the crankset’s exterior, providing a seamless fit with the original crank. For riders navigating deep mud or extreme conditions, pairing this ring with a chainguide or chainkeeper is recommended for maximum retention.
