Genesis Croix de Fer 931 Frameset

Genesis loves steel, and so do we - especially stainless steel. The Genesis Croix de Fer 931 is a premium gravel frameset in Reynolds 931 stainless steel for those who want to build a fast, durable, and versatile bike for gravel, touring, and long days on mixed terrain.

Reynolds 931 combines high strength and stiffness with excellent corrosion resistance. The modern Croix de Fer platform has a T47 threaded bottom bracket, a tapered head tube, and 12 mm thru-axles. The Amplitude G200 carbon fiber fork keeps the weight down and has mounts for extra cargo.

With tire clearance for up to 700x47c, internal cable routing, and the option to fit a dropper post, the Croix de Fer 931 can be built in many ways - from a fast all-road and gravel bike to a more heavily loaded touring or bikepacking build. The frame also has mounts for luggage racks, mudguards, and bottle cages.

The Croix de Fer 931 is an excellent foundation for a custom build where material, ride feel, and long service life guide the component choices. If you want to build a complete Genesis Croix de Fer, we’d be happy to help with sizing, wheels, drivetrain, and other components.
