Wolftooth DM RaceFace Cinch Revolution Bikes March 2, 2015 Wolftooth Drop Stop Rings The Wolf Tooth Cinch rings feature a our patent pending Drop-Stop asymmetrical tooth design for the best wear life, chain retention and mud clearance. Also our rings in sizes 26-34 have an ideal 49mm chainline vs the Race Face direct mount ring chainline of 51mm. Our 36T ring has a 51 mm chainline to provide adequate chainstay clearance. Use a 10 or 11 speed chain. If using a 9 speed drivetrain, plan to use a 10 speed chain (it will shift great), as the 9 speed chain fits too loosely on the ring. Product weights: 26t – 48g, 28t – 54g, 30t – 58g, 32t – 63g, 34t – 69g, 36t – 75g Color: Black For more information please contact your local dealer. Or us directly from our contact page.
