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. The Seek 430 PM fork has 6 x M5 mounting points on each side, with a recommended load capacity of 3 kilograms across three mount points. The newer Seek 430 FM fork has unique thru-mounts made from 6061-T6 alloy. The mounts are supported by both sides of each fork blade, and they have a larger surface area - this results in a stronger, more durable mounting interface. This fork can safely carry a load of 7 kilograms each side, a whopping 14 kilograms in total.
Frame Sizing
The GMX+ ranges from size XXS to XXL, including an XM (extra medium) option, with clearance for up to 3" tyres. Sizes SM–XXL are designed around 29" wheels, while XXS and XS frames run 27.5" wheels, ensuring geometry proportions and handling characteristics are consistent across all sizes.
