Wolf tooth 4B 110 BCD Oval Chainring, Black

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.

Specifications:

– Weight: 38t – 66g

Compatibility:
– These rings are for use with 110 BCD 5 arm cranksets.
– Crank arm clocking arrow will be rotated 180 degrees from normal on cranksets that have 4 bolts visible and 1 hidden bolt behind the crank arm like for SRAM.
– Wolf Tooth’s patented Drop-Stop® wide/narrow tooth profile for the ultimate chain retention and mud shedding ability
– Chainline – varies – these rings can be mounted in either the big or small ring position on a double cranksets. The most common mounting is in the big ring position because of chainstay clearance. The ring centerline is ~2mm from the ring’s mounting face so they usually sit about 2mm closer to the frame than the stock big ring (depends on the stock ring)
– Can be mounted in either the big or small ring position of a double crankset given chainstay clearance in the small ring position.
– Stock 2x bolts will not work. You will need bolts like our 6mm bolts which are optimized for single ring mounting.
– Use Drop-Stop B for all 9, 10, and 11spd chains or 12spd SRAM Eagle, SRAM Flattop, Campagnolo, KMC, Connex or Wippermann chains
