Product Details

More power? Check. Better traction? Definitely. Less shifting? Yup. Funky uneven pedal stroke? Not with Wolf Tooth’s PowerTrac Elliptical™ (PTE) chainrings. Our proprietary design means a slightly less ovalized ring (10%) with less aggressive timing (112°) than 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.

It’s like having two chainrings in one! 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 body’s natural biomechanical Power: For example, during this section, a 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 34t ring is equivalent to a 32t round ring.

Compatibility

• These rings fit on the Shimano XT M8000, SLX M7000, Deore M6000 or FC MT5100 1x or 2x cranksets 
• Not compatible with Deore triple (3x) cranksets
• Use with 9, 10, and 11spd chains or 12spd SRAM Eagle, KMC, Connex or Wippermann chains
• If using a 9-speed drivetrain use a 10-speed chain (shifts and works well on a 9-speed drivetrain and fits the ring tighter for better chain retention)
• Not compatible with Sram Transmission (T-type) and road Flattop or Shimano HG+ 12-spd
• Material: 7075-T6 aluminum
• Weight: 30t • 41g | 32t • 50g | 34t • 59g
