GnarWolf Chainguide ISCG 05 Mount


If you are a rider that fearlessly takes the tough lines and can't afford to drop a chain, the Wolf Tooth GnarWolf™ chainguide is for you. Designed specifically around 1x wide/narrow chainrings like our patented Drop-Stop® chainrings, the GnarWolf will keep you chain glued to your chainring in the roughest and muddies of conditions. Refer to image on this page for installation and adjustment instructions.

The GnarWolf™ features:

  • Infinite chainline adjustment between 48mm and 54mm via an elliptical expanding mandrel. There are no shims required!  
  • Infinite vertical adjustement between 28t and 36t round rings (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 adjustments.
  • All adjustments made with common 4 mm 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 elliptical/oval and round chainrings.
  • Installation takes just a few minutes -- no need to remove your crank arms.
  • Patent pending design.
