Wolf Tooth Race Face Cinch Direct Mount Chainring

These chainrings are for Race Face Cinch cranks such as Turbine, Next SL, Sixc & Aeffect. The Wolf Tooth Cinch chainrings feature patented Drop-Stop® tooth profiles for the best wear life, chain retention and mud clearance. Wolf Tooth optimized tooth profiles for SRAM T-Type Transmission, Shimano Hyperglide+, and all 11, 10, and 9-speed chains.

Drop-Stop A

The original Drop-Stop tooth profile. The wide teeth are wider than Drop-Stop B. Outside faces of narrow and wide teeth guide chain alignment.

Drop-Stop B

Tooth shape is nearly identical to Drop-Stop A, but has narrower teeth. Valley between teeth is deeper to accommodate larger rollers on Flattop chain. Outside faces of narrow and wide teeth touch chain to guide alignment.

Drop-Stop ST

Narrower teeth than Drop-Stop A. Wide teeth use Symmetric Trapezoidal (ST) profile to match extended inner edge on chain to create alignment (outside faces of wide teeth do not touch). Interaction of narrow teeth and chain are similar to Drop-Stop A and B.

• If you plan to ride in very muddy conditions, Wolf Tooth recommends 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 for the best chain security
