The new 1x V3 CX guides improve upon our original, pioneering model that’s been securing drivetrains from Iowa corn fields to beer-soaked Belgian mud pits for years. New for the V3 is our co-molded TR upper guide that is both lighter and quieter than that used on the outgoing model. Adjustment and alignment has been improved with dedicated models for 34.9 and 31.6mm seat tubes as well a sliding lateral adjustment to perfectly dial the guide in for your chainline. We’ve ditched the former alloy seat clamp assembly for a light and stiff carbon version. Additionally, we now have a braze-on tab mount option that - although barely registering on a scale - gives you chain security and peace of mind that a retention ring alone could never provide.
