Curve GMX+ Steel

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!

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.

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.

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 info on the GMX+ geometry click HERE!

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.

With a wide range of frame and fork mounted rack systems on the market, and with more appearing every week, it is important to understand which rack systems are compatible with your Curve frame and fork, and how to mount them correctly in order to ensure safe riding, avoid damage and voiding your warranty. Before mounting a rack, we strongly recommend you get in touch with us to confirm compatibility and the correct mounting procedure. This will minimise the risk of injury, product damage and voiding your warranty. Your local Curve dealer, or the team at Curve HQ, can also help you select a rack system and mount it to your bike for you.
