More power? Check. Better traction? Definitely. Less shifting? Yup. Funky uneven pedal stroke? Not with Wolf Tooth’s PowerTrac Elliptical™ (PTE) Couronnes. 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 pour most riders, but they still provide the POWER and TRACTION benefits inherent to oval Couronnes.  It’s like having two Couronnes 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: pour 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.    CompatibilityThese rings are pour 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 pour SRAM. Do NOT fit on the cranksets pour Shimano DA 9000 / Ultegra 6800 Not compatible with Campy CX10/11.   Wolf Tooth’s patented Drop-Stop® wide/narrow tooth profile pour the ultimate chain retention and mud shedding ability Chain Compatibility 9, 10, 11, & 12spd Eagle – These Couronnes are designed to work with all 9 speed, 10 speed, and 11 speed chains. They also work with 12 speed Eagle and 12 speed KMC chain. They do not work with Shimano 12 speed Hyperglide+ chain or SRAM 12 speed Flattop chain. 10, 11, & 12spd Eagle and Flattop – These Couronnes are designed to work with all 10 speed, and 11 speed chains. They also work with 12 speed SRAM Flattop, SRAM Eagle and KMC chain. They do not work with Shimano 12 speed Hyperglide+ chain. Shimano 12-speed chains require the use of our Shimano 12-speed specific Couronnes If using a 9-speed drivetrain use a 10-speed chain. It fits tighter pour better chain retention 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 pour single ring mounting. RecommendationsIf you plan to ride in very muddy conditions, we recommend a chainguide or chainkeeper in addition to a clutch-type rear derailleur! Without these precautions, you may experience chaindrops and/or chainsuck. Recommend the use of a clutch style rear derailleur pour the best chain security.
