FAQs
FAQs
The reach on the geo chart looks long. What size is good for me?
The short answer is that the reach number may be somewhat deceiving as the frame is designed to be run with a shorter stem. That, in combination with the comparatively steep seat angle, reduces the effective reach of the frame.
Please reach out to sales@curvecycling.com if you have any questions about sizing.

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 Bar
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. More details visit the Walmer Bar page.

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.

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.
