Looking for a 1X chainring for your new Shimano XT, SLX or Deore crankset with the proven chain retention of our Drop-Stop® chainrings? Wolf Tooth has what you need in the form of a beautifully machined asymmetrical 96 mm BCD that provides the ideal 1X chainline of 49mm. The Drop-Stop® tooth design is the best performing on the market, with exceptional durability.
- Drop-Stop technology: On Wolf Tooth’s patented wide/narrow chainring, the wide side of the tooth has maximum contact on the drive side which spreads the load and improves chainring life. The narrow side allows clearance for mud and debris which reduces friction.
- Alternating wide/narrow tooth pattern prevents chain derailment.
POWERTRAC ELLIPTICAL
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.
COMPATIBILITY
- These rings fit on Shimano XT M8000, SLX M7000, and Deore M6000 cranksets.
- Designed to meet the requirements for E-bike use.
- Chainring Bolts: 10mm bolts are optimized for mounting this ring
- Drop-Stop A models will reduce the chainline (inward towards the frame) from the Shimano specified chainline for the crankset: 30T-34T = -2mm, and 36T-38T = -1mm
- Drivetrains: 1x9, 1x10, 1x11 and 1x12 drivetrains. Not compatible with SRAM Flattop AXS or Shimano HG12+ chains.
- If using a 9-speed drivetrain, use a 10-speed chain. It fits tighter for better chain retention.
DROP-STOP TECHNOLOGY
Wolf Tooth’s patented Drop-Stop® wide/narrow tooth profile delivers ultimate chain retention and mud shedding ability. See below for Drop-Stop A compatibility.
RECOMMENDATIONS
- We recommend the use of a clutch style rear derailleur for the best chain security.
- If 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.
