Built to keep your chain secured on the muddiest courses and gnarliest routes, the GnarWolf is at once lightweight, extremely stiff and easily adjustable to fine-grade increments. Make dropped chains a thing of the past with this highly durable, precision engineered guide.

Whilst wide-narrow 1x chainrings do a great deal to prevent chain drop, on the toughest, muddiest trails, a chainguide is sometimes necessary to ensure you’re maximising time spent riding.

Wolf Tooth has crafted the GnarWolf from the ground up as the very best chainguide for use with wide-narrow chainrings on 1x set ups. Refined through extensive use in ice-cold wild winters, this high direct mount GnarWolf fits a wide range of setups – anything from 48mm and 54mm chain lines and 28t - 36t round or 28 - 34t oval chainrings are good to go.

All adjustments are made using a 4mm Allen key and a single screw flips the mechanism upwards, enabling you to remove the chain without interfering with the chainguide’s position.
