WOLF TOOTH Race Face Cinch Direct Mount Chainring 28T

These chainrings are for Race Face Cinch cranks such as Turbine, Next SL, Sixc & Aeffect. The Wolf Tooth Cinch rings feature our patented Drop-Stop® design for the best wear life, chain retention and mud clearance. We have both Boost and standard chainrings. Compatibility: - Any Race Face Cinch™ system crankset. - Wolf Tooth’s patented Drop-Stop® wide/narrow tooth profile for the ultimate chain retention and mud shedding ability - Both standard (142mm rear hub spacing) and Boost (148mm hub spacing) offsets available. - If using a 9-speed drivetrain use a 10-speed chain (shifts and works well on a 9-speed drivetrain and fits the ring tighter for better chain retention). - Chainline - Standard Offset 49mm for 26-34t, 51mm for 36t for additional chainstay clearance - Boost Offset 52mm Available in two different tooth profiles for optimal performance based on your chain type. Use Drop-Stop ST for use with Shimano 12-speed Hyperglide+ chains. Use Drop-Stop A for all 9, 10, and 11spd chains or 12spd SRAM Eagle, KMC, Connex or Wippermann chains. - 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. - Recommend the use of a clutch style rear derailleur for the best chain security. Specifications: - Weights: 28t- 54g - Material: 7075-T6 aluminum
