Wolf Tooth Elliptical - Single Chainring 64mm - Drop Stop - black

Wolf Tooth Elliptical - Single Chainring 64mm - Drop Stop - black

The oval Wolftooth 64 mm BCD Single chainrings are the perfect solution when you need a little lower gearing on your 104/64 BCD crankset. In addition the universal models fit both 104/64 BCD cranksets and the Shimano XT (M8000) and SLX (M7000) 11-speed cranks with 96/64 BCD.

Wolf Tooth won't try to convince you that elliptical (or oval, the same thing) chainrings will change your life...but they might! What the engineers of Wolf Tooth can say for sure is that their Powertrac rings have a different feel from round rings and can provide an efficiency benefit and smoother power output for some riders. Testers report the biggest benefits on punchy singletrack and hills, allowing less shifting and faster acceleration.

Of course the Single chainrings feature the patent-pending Drop-Stop® Narrow Wide tooth design for ultimate chain retention and mud shedding ability. Wolf Tooth recommends to pair the chainrings with the 104 BCD bash ring for best appearance and to protect the 104 BCD spider arms.

  • chain line: 48 mm at 2-speed cranks / 47 mm at 3-speed cranks
  • patented Drop-Stop® Narrow Wide tooth design
  • material: aluminium 7075-T6
  • compatibility: 9 to 12-speed (use of a 10-speed chain for 9-speed drivetrains recommended)
  • fit any crankset that has a 64 mm BCD "small ring" position. Incl. standard 104 mm BCD, the M960 Shimano XTR, the 96 mm BCD Triple (e.g. M782) and some other cranksets


More power? Check. Better traction? Definitely. Less shifting? Yup. Funky uneven pedal stroke? Not with Wolf Tooth’s PowerTrac Elliptical™ (PTE) chainrings. The 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 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.

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.
