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 a front derailleur mount and round and oval chainring sizes 34-62T.
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.

Service for the GnarWolf Chainguide is easy and can be done at home. A 4mm hex key is the only tool required for installation and adjustment.
