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+ is ready for adventure.
This is our ground-up redesign of the perfect bikepacking bike featuring 3.0" tyre clearance and off-set bottle mounts, which allow a full-sized frame bag and three litres of water in the main triangle, even on a small frame. Tested and proven by the Curve Squad on some of the toughest riding conditions on Earth.
Pre-Order now open for an April release date.
What would an "Overlander" ride?
The GMX+ was inspired by the intrepid Overlanders of the 1890s, who rode incredible distances without support across the harsh Australian outback. We wondered what these Overlanders would create if they could build a bike with today's modern technology. The answer is the GMX+: an all-new adventure platform based around wide plus size tyre clearance (up to 3.0"), ultra wide drop bars and innovative new fork geometry.
After each edition of the outback bikepacking race, Race to the Rock, we realised that we wanted more out of our original GMX. So we redesigned it from the ground up to have increased storage capacity, bikepacking specific geometry and clearance for 3.0" tyres - allowing you to tackle a wider range of terrain, including all but the deepest of red desert sand.
Go long and tackle any terrain, the GMX+ is the ultimate OVERLANDER.

Feeling thirsty?
The GMX+ titanium frame and carbon fork can easily accommodate 10+ 1L water bottles on the numerous mounts, including offset downtube mounts which allow you to have two 1L water bottles within reach as well as a full frame bag.
Walmer Bars
The Walmer Bar - Curve’s ultra wide drop bar - is the perfect handlebar to complement rugged off-road riding. These flared dirt drop bars come in 4 sizes (46, 50, 55, 60cm on the hoods), and are just an additional $100 AUD when purchasing a GMX+ frameset online (save $89!). Walmer Bars give the combination of more stability, hand positions and storage space than any other bar out there.
PLUS!!!
With clearance for up to 29 x 3.0” plus size mountain bike tyres (27.5 x 3.0" in sizes XXS–XS) the GMX+ can take you anywhere. Big tyres mean lots of traction and less rolling resistance, allowing you to ride efficiently across terrain such as sand, rocks or snow.
Extended Sizing
The GMX+ ranges from size XXS to XL to allow more adventurous men and women the chance to get off the couch and explore (we even made an 'Extra Medium' size!) Sizes SM–XL are designed around 29" wheels, while XXS and XS frames run 27.5" wheels to keep the geometry proportions and handling characteristics consistant across the sizes.

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. |
