Our new Direct Mount Chainrings for SRAM 8-Bolt Mountain Cranks are optimised for the new SRAM Transmission mountain groupsets and T-Type chains. These are for riders who have the latest SRAM T-Type Transmission groupset and want a different chainring size beyond stock offerings, or who want to upgrade to a Made In USA option with an optimised tooth profile for better performance. The 3mm offset is for SRAM MTB cranks with DUB WIDE spindles that are already at the 55mm chainline required for SRAM T-Type Transmission groupsets. COMPATIBILITY These direct mount chainrings will replace your existing chainring and spider or replace a direct mount chainring for SRAM T-Type Transmission cranksets and other SRAM cranks that use the 8-bolt standard. SRAM T-Type Transmission DUB Wide MTB cranksets use the 8-bolt direct mount standard. Chainline of 55mm with 3mm offset for DUB Wide MTB 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 oval 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. DROP-STOP TECHNOLOGY Wolf Tooth’s patented Drop-Stop® wide/narrow tooth profile delivers ultimate chain retention and mud shedding ability. Drop-Stop B is compatible with all chains except Shimano HG and Campagnolo 13-speed chains. RECOMMENDATIONS We recommend the use of a clutch style rear derailleur for the best chain security. Use the included custom T20 bolts. Torque 4Nm with T20 tool SPECIFICATIONS Weights: 32T • 69g | 34T • 73g Material: 7075-T6 aluminum Made in the USA The Story Wolf Tooth was founded to design and manufacture precision cycling products that emphasize function, performance, and reliability to meet the needs of our fellow racers and riders. We are a group of cyclists in Minneapolis, Minnesota that spend a lot of time talking about bike components. Like most detail-obsessed riders, we're always looking for new products that could make our bikes lighter, faster, more versatile, or more reliable. We pride ourselves on delivering premium products of the highest quality.
