The Genesis Croix De Fer 931 Frameset represents the pinnacle of steel craftsmanship, designed for riders who want nothing less than a high-performance, long-lasting, and beautifully built gravel bike. Constructed from Reynolds 931 stainless steel, this frameset offers a perfect balance of stiffness, responsiveness, and corrosion resistance, ensuring you get a ride quality that is both lively and durable.
At the heart of the build, Reynolds 931 provides an incredible spring-like feel to each pedal stroke, giving riders an unmatched connection to the road or trail. Its stainless properties mean you’ll enjoy a frame that resists rust and wear, making it a true investment piece for years of adventure. The Croix De Fer 931 also integrates a tapered head tube for added stiffness and stability at the front end, perfectly paired with the Amplitude G200 carbon gravel fork for precision control and versatility.
The frameset includes a threaded T47 bottom bracket shell, offering lighter tubing options and wide chainset compatibility. Designed for adaptability, it accommodates up to 700 x 47mm tires, giving you the flexibility to switch between fast all-road slicks or rugged gravel tires depending on your ride style. Internal cable routing ensures a clean aesthetic while being compatible with various drivetrain setups, and it’s dropper-post ready for those who demand added off-road capability.
Whether you’re building a sleek endurance road machine or an unstoppable gravel explorer, the Genesis Croix De Fer 931 frameset is a true dream-build foundation. Its Reynolds 931 tubing is seamless, cold-worked, and nearly indestructible, crafted for performance that lasts a lifetime.
At Stratton Cycles, we know that riders demand both beauty and performance in their builds, and the Croix De Fer 931 frameset delivers both in equal measure. This is more than just a frameset – it’s a canvas for your creativity and passion for cycling. Begin your ultimate build today with the Genesis Croix De Fer 931, and enjoy a ride that’s as timeless as steel itself.

Bikes Delivery Information
Bike & Ride – The Premier Option for You
Stratton is proud to be one of the few online bike retailers in the UK offering a delivery service that guarantees your bike arrives fully assembled and ready to ride. Our premier delivery option, ‘Bike & Ride,’ is available for just £70 per bike and ensures that your biking experience starts effortlessly and smoothly.
With ‘Bike & Ride,’ your new bike will arrive in a specially designed bike box with minimal packaging, ensuring protection during transit while reducing environmental impact. Included are all the necessary tools, so you can start riding within minutes of delivery. Our commitment to sustainability means we avoid using foam, bubble wrap, and zip-ties, opting instead for eco-friendly packaging. We encourage you to recycle any materials where possible, contributing to a greener planet and giving you the added satisfaction of making an environmentally responsible choice.
Bike & Ride for Standard Bikes
For standard bikes, our ‘Bike & Ride’ service ensures that each bike undergoes meticulous assembly and rigorous quality checks by our expert bike builders. This attention to detail guarantees that your bike meets the highest standards of safety and performance. To facilitate this thorough process, bicycles are not eligible for next-day delivery, ensuring each bike is perfectly prepared for you.
Bike & Ride for E-Bikes
Due to the additional weight and unique handling needs of electric bikes, we cannot ship them fully assembled. Instead, our expert mechanics will assemble, configure, and thoroughly inspect your electric bike before repacking it in its original box. This process requires the removal of the front wheel, handlebars, pedals, and seat-post, which you will need to reinstall upon delivery. We provide detailed instructions and all necessary tools to help you complete the assembly quickly and effortlessly.
Experience the unmatched convenience and quality of ‘Bike & Ride’ by purchasing your bike from our online shop. With Stratton, you’re choosing a service that prioritises your riding experience, environmental responsibility, and exceptional quality from the moment you receive your bike.
