The Shimano XTR, XT, and SLX 12spd Hyperglide+ chains work differently than other products on the market so Wolf Tooth engineers developed a completely new tooth profile to provide optimal chain retention and durability when using this new chain technology.

With PowerTrac Elliptical 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 bodys natural biomechanical POWER: For example, during this section, a PTE 32T ring is equivalent to a 34T 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 32T ring is equivalent to a 30T round ring.

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.
