Wolf Tooth Direct Mount Elliptical Shimano Hyperglide+ 12 Speed Chainrings for Shimano Cranks
These chainrings are for Shimano direct mount cranks. The Wolf Tooth chainrings feature the patented Drop-Stopdesign for the best wear life, chain retention and mud clearance.
The new Shimano XTR, XT, and SLX 12spd Hyperglide+ chain works differently than other products on the market, Wolf Tooth havedeveloped a completely new narrow-wide tooth profile to increase durability and provide anoptimal 1-speed chainlinepreventingthe chain from jumping off the chainring.
Features
PowerTrac Elliptical (PTE) rings
More power? Check. Better traction? Definitely. Less shifting? Yup. Funky uneven pedal stroke? Not with Wolf Tooth's PowerTrac Elliptical chainrings.
With PowerTrac Elliptical (PTE) rings, the larger-diameter section of the ring engages with the chain at the optimal point on the downstroke, or "Power Zone," - between 1-5 and 7-11 on a clock face - to take advantage of your body's natural biomechanical power: For example, during this section, a PTE 34t ring is equivalent to a 36t round ring.
Similarly in the "Recovery Zone" (11-1 and 5-7), the smaller section on the PTE ring engages, maximizing efficiency in the weakest part of the pedal stroke; here the PTE 34t ring is equivalent to a 32t round ring.
Wolf Tooths proprietary design means a slightly less ovalized ring (10%) with less aggressive timing (112) than their competitors' versions;any change to your pedal stroke is unnoticeable for most riders, but they still provide the power and traction benefits inherent to oval chainrings.
Additionally, the above provides a smoother, more efficient pedal rotation, which means better traction. Steadier torque on the rear wheel means less spinning out in the "Power Zone," while pedaling is easier during the "Recovery Zone," so you maintain momentum.
