Wolf Tooth 104 BCD Elliptical Oval Narrow Wide
Wolf Tooth 104 BCD Elliptical Oval Narrow Wide
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 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.
Chainline (approximate as BB centering and cranksets vary) - 48mm on 3x cranksets and 49mm on 2x
Compatibility
- These rings fit any 104 BCD crankset
- Wolf Tooth’s patented Drop-Stop® wide/narrow tooth profile for the ultimate chain retention and mud shedding ability
- For 1x9, 1x10, 1x11 and 1x12 drivetrains (including SRAM Eagle)
- 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).
- Quarq power meter compatible with sizes 34t and 36t. Filing required for 32t fitment onto some older Quarq Power meters. No modifications are required for the DUB Quarq Power meter.
- Threaded to use M8 chainring bolts (no nuts required)
- Ovality of 10% and timing of 112° after TDC (top dead center)
- Maximum diameter is that of a chainring 2t bigger than the size you order (so be sure there is adequate chainstay clearance.)
-
Available in two different tooth profiles for optimal performance based on your chain type. Use Drop-Stop ST for use with Shimano 12-speed Hyperglide+ chains. Use Drop-Stop A for all 9, 10, and 11spd chains or 12spd SRAM Eagle, KMC, Connex or Wippermann chains.
