What are the main differences between the original GMX and the GMX+? The GMX+ is a completely new design with a much slacker geometry, designed around a 1x drivetrain, more cage mounting points (7 on frame, plus fork mounts), boost spacing (15x110 & 12x148 mm TA) with room for 3.0" tyres and a completely new non-suspension corrected carbon fork. We've also designed our Walmer Bars to complement this platform perfectly. We’ve rerouted the cables to the down tube instead of the top tube, added a T47 BB shell and an oversized seat tube for added stiffness.
Can I run a suspension fork on the GMX+? No, it'll mess with the geo. You can run a squishy fork on the UpRock or the DownRock.
How do I get the Walmer Bar discount? Add a GMX+ Frameset and a set of Walmer Bars to your cart and the discount will automatically apply at checkout. You can find Walmer Bars in the Parts section of our webshop.
When shipping direct, how does a complete bike come finished to me? Each bike is built and boxed to "90% complete" with the fork steerer uncut and bar tape is not wrapped. We do this so each individual can personalise their setup options. This final procedure should be performed by an experienced bike mechanic.
