We’ve made it something of a tradition to give a frameset to one of our Bikepacking Collective members to coincide with each new issue of our biannually printed publication, The Bikepacking Journal, and we have something extra special this time around. We’ve teamed up with our friends at Melbourne-based Curve Cycling to give one lucky supporter an all-new GMX+ Steel frameset in their choice of size and color, valued at around $2,500 AUD ($1,900 USD).
As the name implies, the yet-to-be-released (or even officially announced) Curve GMX+ Steel is a steel version of their unique titanium GMX+, which made quite a splash in the bikepacking world when it was released around this time last year. Both bikes have identical frame specs, including a whopping seven sets of bottle cage mounts, clearance for 3.0″ tires, and T47 bottom bracket shell. And like its titanium counterpart, the new GMX+ Steel comes with a full-carbon GMX+ fork.
Introduction to the GMX+ Platform
Following several editions of Race to the Rock across the Australian Outback, the design team at Curve realized they wanted to develop a bike that could push beyond the capabilities of the original GMX drop-bar 29er (which we reviewed back in 2018). After a complete redesign, the GMX+ was born, featuring additional storage capacity, bikepacking-specific geometry, and bigger tire clearance. They call it the ultimate overlander, and it was designed to feel equally at home with drop bars or flat bars, depending on how you like to ride.
As the crew at Curve puts it, “The GMX+ was inspired by the intrepid Overlanders of the 1890s, who rode incredible distances without support across the harsh Australian outback. We wondered what these Overlanders would create if they could build a bike with today’s modern technology. The answer is the GMX+: an all-new adventure platform based around wide plus size tyre clearance (up to 3.0″), ultra wide drop bars and innovative new fork geometry.” The new GMX+ takes all the research, design, and testing that went into the GMX+ and offers it in a more affordable package.
Curve GMX+ Steel Specs
Estimated to begin shipping around the end of the year, the Curve GMX+ Steel will be available in sizes XS to XL. The first batch will be available in either Pink Roadhouse or Nitro Chocolate, the two colors pictured here. Frames will be built with Columbus Cromor steel tubing paired with the GMX+ fork, which was designed specifically to work in unison with the GMX+ frame. Full specs include:
- 7 cage mounts
- Rear rack mounts
- Clearance for 3.0″ tires
- T47 bottom bracket
- 15×110 & 12x148mm TA spacing
- Full-carbon GMX+ fork
