Curve GMX+ Frameset

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.

• Carry More

  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. The Seek 430 fork has 6 x M5 mounting points on each side, with a recommended load capacity of 3 kilograms across three mount points.

• Walmer Bars

  Our Walmer Bar, is the perfect companion to the GMX+ as it was originally designed to work together with the GMX+ frame and SEEK 430 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.

• 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.

• 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.
