Push your cycling performance to the limit with the Wolf Tooth Gnarwolf Chainguide Seat Tube Clamp Mount, a well-crafted addition to any bike looking to conquer the toughest routes and muddiest trails. Say goodbye to the inconvenience of dropped chains, as this essential piece of drivetrain spare embodies resilience, precision, and remarkable adjustability.

Despite the trend towards wide-narrow 1x chainrings to minimize chain drop, nothing beats the reliability of a chainguide in ensuring continuous riding on challenging terrains. The Gnarwolf Chainguide from Wolf Tooth is specifically crafted for this purpose, while still being fully compatible with wide-narrow chainring 1x set-ups. Tested in extreme conditions to secure a high level of performance, this chainguide is suited for a broad array of setups - from 45mm-51mm chain lines to 34t-52t round or oval chainrings.

Ease of use is another area where the Gnarwolf Chainguide excels. All adjustments can be made using a simple 4mm Allen key, and a unique single-screw mechanism flips the guide upwards, allowing for quick and easy removal of the chain without disturbing the chainguide’s position.

Key Features:

  • Designed to stop chain drop on demanding and muddy routes
  • One-of-a-kind adjustability with simple chain removal
  • Construct from durable 6061-T6 aluminium

  • Requires a minimum distance of 10 mm between the crank and centre of the ring

  • Suitable for 45mm-51mm chain lines and 34t-52t chainrings
