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 utilised in the updated skid - making the best even better.

"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.
