Wolf Tooth Gnarwolf Chainguide ISCG05 Mount rev2

Ultimate Chain Retention

The Wolf Tooth GnarWolf Chainguide rev2 is designed for maximum chain retention for mountain biking, extreme gravel, and particularly rough CX races. It is compatible with most bikes using 1x drivetrains that have an ISCG-05 mount and round and oval chainring sizes 28-34T.

Simple Adjustability

The base of the GnarWolf allows for the vertical adjustment necessary for differing chainring sizes, while the GuideLock Quick Adjustment System moves the chainguide head to accommodate chainlines from 45-51mm. Adjusting the GuideLock Quick Adjustment System requires just a 4mm hex to operate an expanding elliptical mandrel to move the head securely into place without the use of shims.
