Curve GMX+ Steel Frameset - Nitro Chocolate

Built on the success of its titanium GMX+ cousin, Curve is proud to present the GMX+ Steel. After three years of development and testing, Curve's steel bikepacking bike is finally available in two colourways.

Introducing the Curve GMX+ Steel in vibrant Roadhouse Pink. This iconic colourway pays homage to the sun-faded pink paint of the legendary Pink Roadhouse in Oodnadatta. It's a hue that captures the spirit of the outback, where the scorching sun leaves its mark on everything it touches. Alternatively, the Nitro Chocolate colourway is a mesmerising fusion of rich chocolate brown with a subtle sparkle that evokes the enchanting play of moonlight on a remote Gibber Plain. It's like having a taste of Outback Australia's magic with you as you ride.

The GMX+ is inspired by the intrepid Overlanders of the 1890s, who covered incredible distances across the harsh, barren Australian outback without support. The GMX+ is a modern adventure bike designed with wide tyre clearance thanks to our innovative carbon fork, ultra-wide drop bars for stability, numerous mounting points and generous amounts of room for carrying water or other gear.

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. It's our very own reimagination of a bikepacking bike. In recent years, the GMX+ has taken on some of the most challenging races worldwide, including the Tour Divide, Silk Road Mountain Race, and Race to the Rock.

Load Up

The GMX+ Steel lets you carry more water and pack more gear. The steel frame includes mounting points on the rear stays and offset mounts on the downtube, allowing riders to run a full-size frame bag plus 1 litre bottles to either side. The Seek 430 FM fork has 4 x M5 heavily reinforced mounting points on each side, with a recommended maximum load capacity of 7 kilograms across three mount points (on each side). You read this correctly - it's a carbon fork able to carry a remarkable 14 kilograms of load safely!

Class Leading Carbon Fork

Our Seek 430 FM fork has been made to work in unison with our GMX+ (Ti & Steel) framesets and our popular Walmer Bar and Remlaw Bar. It improves on the original Seek 430 fork with updated brake hose and dynamo cable routing, the introduction of flat mount brakes and the addition of four heavily reinforced M5 mounting points per fork blade that can carry up to a whopping 7 kg each (maximum) when secured across three mounts! That's a total of 14 kg that can be safely carried on the Seek 430 FM! To achieve this, we left the industry-standard rivnuts behind and instead developed our own unique thru-mounts, completely re-thinking the way the mounts are added to the fork blade.

Drop Bar, Flat Bar or Riser Bar?

The GMX+ Steel 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 will also work well but may require a longer stem. Due to the low front end on the GMX+ Steel, which isn't corrected for suspension, an even more relaxed touring position is possible with a high-rise flat bar.

Frame Sizing

The GMX+ Steel ranges from size XS to XL. Sizes SM–XL are designed for 29" wheels. 27.5" wheels are required for size XS to ensure optimal performance. For more information on the GMX+ geometry click HERE!
