Genesis Croix de Fer 725 (Massive Li-Lac) Frames

The Genesis Croix de Fer 725 is a gravel frameset for building a bike that can start out as a fast gravel bike, get fenders and a rack for everyday use, then be loaded up for several days on the road. The Reynolds 725 steel frame delivers the classic Croix de Fer feel, with modern standards for a truly versatile custom build.

The heat-treated Reynolds 725 frame is paired with an Amplitude G100 Cr-Mo fork, Flat Mount disc brakes, and 12 mm thru-axles. With clearance for 700x47 mm tires, internal cable routing, and support for both 1x and 2x drivetrains, you can build anything from a fast all-road or gravel bike to a touring or bikepacking rig.

Mounts for full-coverage fenders, a rack, multiple bottle cages, and extra cargo on the fork make the Croix de Fer 725 unusually versatile. The Massive Li-Lac paint with black graphics also gives the frame just the right amount of personality without dictating how the rest of the build should look.

Choose the Croix de Fer 725 if you want more cargo-carrying options and long-term usability than a dedicated race gravel bike, but a more modern and nimble bike than a traditional touring build. If you’d like to build a complete Croix de Fer, we’d be happy to help with sizing, wheels, drivetrain, and components.
