The GnarWolf Chainguide ISCG-05 rev2 is designed for maximum chain retention while mountain biking or racing particularly rough gravel and CX. It is made for any bike that has ISCG-05 mount and a 1x drivetrain. The GnarWolf Chainguide will keep your chain on your chainring in the roughest and muddiest of conditions. Refer to image on this page for installation and adjustment instructions.  

• 8mm of chainline adjustment via our GuideLock quick adjustment system. No shims required.
  Infinite vertical adjustment between 28 and 36T for round chainrings and  28-34T oval chainrings
• Loosen one screw to flip the guide out of the way for easy chain removal without losing any of the guide's adjustments
• All adjustments made with common 4mm hex key
• Designed for the rigors of Enduro, heavy trail, mud and even DH riding, the Wolf Tooth engineers made this guide extremely stiff and strong while keeping it light at 44g
• Specific guide shaping is optimized for use with oval and round chainrings
• Installation takes just a few minutes – no need to remove your crank arms
