Race Face Cinch Oval Drop Stop Chainring Boost (3 Mm) Offset Shimano Hg+

These chainrings are for Race Face Cinch cranks, such as Turbine, Next SL, Sixc & Aeffect, and feature our patented Drop-Stop® design for the best wear life, chain retention and mud clearance. The 3mm offset of this chainring suits Boost drivelines.

Drop-Stop ST Chainrings are only compatible with 12-speed Shimano HG+ and KMC 12-Speed chains. 

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.

CHOOSE YOUR OFFSET

• Standard MTB: 6mm offset for non-Boost mountain bikes, GXP and long spindle BB30 cranks for 49mm chainline
• Boost: 3mm offset for 52mm chainline

DROP-STOP TECHNOLOGY

Wolf Tooth’s patented Drop-Stop® wide/narrow tooth profile delivers ultimate chain retention and mud shedding ability.

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.
• For a longer lasting and more durable option, check out the CAMO System that offers stainless steel chainrings.
