If you're a rider who fearlessly tackles challenging lines and can't afford to drop a chain, the Wolf Tooth GnarWolf® chain guide is for you. Designed specifically for any bike fitted with an ISCG 05 mount and a 1x narrow/wide chainring. The GnarWolf will keep your chain glued to your chainring in the toughest and muddiest conditions. Refer to the image on this page for installation and adjustment instructions.

Patented infinite chainline adjustment between 48 mm and 54 mm via an elliptical expanding mandrel. No shims required.

Infinite vertical adjustment between 28t and 36t for round chainrings and 28t-34t elliptical

Loosen one screw to flip the guide out of the way for easy chain removal without losing any of the guide's settings

All adjustments are made with a common 4 mm hex key

Designed for the rigours of enduro, heavy trail, mud, and even DH riding, Wolf Tooth engineers have made this guide extremely rigid and strong whilst keeping it lightweight at 44 g.

The specific shape of the guide is optimised for use with elliptical and round chainrings

Installation takes just a few minutes: no need to remove your cranks
