Curve Kevin of Steel Frameset

The main frame triangle is comprised of Columbus Zona Italian-made double-butted tubing. Zona allows for the ideal compromise between weight, strength and life of the frame.

The Ride 400 fork has clearance for wheel options based on your riding style. For example, Kevin can run either 700c wheels with 32–45 mm tyres, best suited for commuting, gravel, and cyclocross, or if you’re looking to tackle some rougher terrain with more traction, use 650b (27.5”) wheels fitted with 1.8–2.2” tyres. Curve has the above wheel options in both carbon and aluminum available.

The custom 4130 steel yoke design allows Kevin to run some super wide gravel tyres in two wheel sizes, and also stiffens the BB area to avoid frame flex under load.

Our Ride 400 fork, originally titled GXR fork, was built to complement the Kevin of Steel and titanium GXR frameset. Featuring 3 x 12 mm M5 mounting points on each blade, the Ride 400 fork can accommodate anything from extra water bottles, our Rocket Pooches, or any other micro pannier or fork-specific bag.

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.
