Wolf Tooth - Direct Mount Chainrings for Race Face Cinch

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.
