G4 Carbon

The new G4 picks up where the famous G3 left off -- three consecutive appearances in the Dirt 100 issue, as well as countless World Cup and FMB podiums made it the most sought after full-featured guide on the market. Upgrades to the G4 include a new co-molded upper guide that utilizes a softer durometer TPU material on the interior walls and ceiling to silence drivetrain chatter. An improved material formula is utilized in the updated skid -- making the best even better.

NEW Full-size, nylon upper guide with co-molded TPU material on the interior walls and ceiling that silences chain contact

Integrated skid protects chainrings and glides over rocks and obstacles

Includes standard pulley and new G-slide slider block for quiet, dependable operation in muddy and dank conditions.

Tracked and grooved upper guide / backplate interface increases stiffness and eases installation

Available in "Mini" 32-36t and "Mega" 36-40t sizing

All install and adjustment operations possible with just a single 4mm HEX wrench.

BB mounted guides are only compatible with traditional, threaded BB systems

Compatible with chainlines 50mm and wider (55mm and wider on 83mm BB shells)

  • 153g (Mini Carbon ISCG)

"You may just be the type of rider that should be using some sort of chain guide. Some people, especially those who are pushing hard and going fast over rough terrain, are just always going to need some sort of chain guide." - Mike Levy, Pinkbike 2015.
