We Say...

We are proud to be a Curve dealer in the U.K! We like how Curve straddle the line between party and race, a brand that has riding fast in its DNA, but with equal parts adventure and fun thrown in too.

The GMX+ is a roudy adventure bike, with progressive geometry that is meant to be ridden hard over any terrain you may encounter!

They Say...

What would an "Overlander" ride?

The GMX+ is inspired by the intrepid Overlanders of the 1890s, who covered incredible distances without support across the harsh Australian outback. We have designed a bike that can do the same, but with much more ease using today's modern technology. The GMX+ is an adventure bike designed with wider tyre clearance thanks to our innovative carbon fork, ultra-wide drop bars for stability, and numerous mounting points for storage or water.

Tested in real-life conditions, the original GMX was designed for Race to the Rock, a harsh, remote desert race in Australia. With testing came improvements to the bike geometry and fork clearance, and so the GMX+ was born.

In recent years, the GMX+ has taken on some of the most challenging races worldwide, including Tour Divide, Silk Road Mountain Race, and Race to the Rock.


  • Load Up

    The GMX+ lets you carry more water or load more gear. The titanium frame includes mounting points on all rear stays and offset on the downtube, allowing riders to run a full-size frame bag plus 1 litre bottles to either side. Furthermore, the newer model Seek 430 FM fork, features 4 x M5 mounting points on each blade, and can accommodate anything from extra water bottles, our Rocket Pooches, or any other micro pannier or fork-specific bag.  Please keep in mind that it is designed to carry a max weight of 14 kg (7 kg/ blade across three mounting points).

  • Walmer Bar

    Our Walmer Bar, is the perfect companion to the GMX+ as it was originally designed to work together with the GMX+ frame and our non-suspension-corrected SEEK 430 FM fork as an Off-Road touring system. This flared drop bar is available in several sizes and will provide the rider with more stability, hand positions, and storage space than other available handlebars. More details visit the Walmer Bar page.

  • Frame Sizing

    The GMX+ ranges from size XXS to XXL, including an XM (extra medium) option. Size SM–XXL is designed around 29" wheels, while XXS and XS frames run 27.5" wheels, ensuring geometry proportions and handling characteristics are consistent across all sizes.

    There is ample room for bikepacking bags on all frameset sizes. To make sure current, prospective or custom bagging fits your frame size please see our Bagmaker Drawing page.


                 Want to Carry More?

    • With a wide range of frame and fork mounted rack systems on the market, and with more appearing every week, it is important to understand which rack systems are compatible with your Curve frame and fork, and how to mount them correctly in order to ensure safe riding, avoid damage and voiding your warranty. Before mounting a rack, we strongly recommend you get in touch with us to confirm compatibility and the correct mounting procedure. This will minimise the risk of injury, product damage and voiding your warranty. Your local Curve dealer, or the team at Curve HQ, can also help you select a rack system and mount it to your bike for you.


      Custom Rohloff, Pinion or Effigear Build

      • Did you know that we offer custom build options for our GMX+ Ti to support Rohloff internally geared hubs as well as Pinion and Effigear gearboxes for either chain or belt drive? To effectively use a Rohloff or gearbox, you need a way to tension the chain or belt. There are a few ways to achieve this, but the straightforward and most reliable way in our opinion is via adjustable dropouts. We have developed our own sliding dropout system, with a range of inserts, that can accept various wheel, axle and brake types. The gearbox-compatible version of our GMX+ comes with a 3D-printed yoke behind the gearbox case which helps us achieve the frame stiffness required for a gearbox with belt drive. The Rohloff-compatible version comes with sliding dropout inserts that work seamlessly with a standard Rohloff Speedhub in QR-configuration. We can offer inserts for use with either Post Mount or Flat Mount brake calipers. For belt drive compatibility we also add an almost invisible split in the seat stay. Frames supporting internal gear systems are made to order, with a lead time between six and nine months. There is a surcharge for these custom options. Get in touch to learn more about pricing and current lead times.

    • Drop Bar or Flat Bar?

      The GMX+ can accommodate a drop bar or flat bar. Any wide drop bar, especially our Walmer Bar, will work with a shorter stem, as will our unique Remlaw Bar. Other flat bar designs may also work well, but a longer stem length may be needed.
