GMX+ Frameset

The GMX+ is the ultimate titanium bikepacking bike. Whether it’s an overnight gravel grind, ultra-endurance racing like the Tour Divide, or off-road touring through the desert, the GMX+ can fit 3.0" tyres, carry loads of water and ready for adventure.

The GMX+ Fork

The GMX+ Fork has been specifically designed to work in unison with the GMX+ frame and Walmer Bars.

The lowest possible axle to crown height (430mm) allows for the best use of storage space within the front triangle.

The 55mm fork offset combined with GMX+ frame geometry has been selected to deliver a handling characteristic that's stable at speed, yet direct and nimble in challenging terrain.

The 12 x M5 mounts are perfect for Rocket Pooches or extra bottle cages.

Geometry

We've designed the GMX+ to run either flat bar or drop bar. Above you can see Jesse's loaded GMX+ utilising the Walmer Bars. In the second image, Sarah stands beside her GMX+ in flat bar mode.

FAQs

What are the main differences between the original GMX and the GMX+? The GMX+ is a completely new design with a much slacker geometry, more cage mounting points (7 on frame, plus fork mounts), boost spacing (15x110 & 12x148mm TA) with room for 3.0" tyres and a completely new non-suspension corrected carbon fork. We've also created our own ultra wide drop bars (Walmer Bars!) designed to complement this platform. 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 both a GMX+ Frameset and a set of Walmer Bars to your cart and the discount will apply automatically at checkout. You can find Walmer Bars in the Parts section of our web shop.
What groupsets can I use on the GMX+? You can run the GMX+ with flat bars or drop bars, but there are a few things to be aware of when collecting parts for your build: The GMX+ is designed for 1x cranks only. This is because the seat tube design won’t allow a front derailleur in the correct position. A 2x or double crank will reduce tyre clearance. When selecting cranks, make sure they are suitable for a 73mm BB shell, this is a MTB standard, not road and they have a 52mm chainline. Lastly, brake calipers must be Post Mount. Most drop bar levers come with Flat Mount calipers, so be careful to select the correct brakes for your GMX+. As always, reach out if you need any assistance.
