Croix De Fer 12/12 725 Frameset Large – Ultimate All-Terrain Bicycle Frame with Modern Features
Introducing the Croix De Fer 12/12 725 Frameset Large, your next go-to choice for an all-terrain bicycle frame that blends modern technology with classic durability. Designed for the discerning cyclist, this frameset is constructed from high-quality Reynolds 725 tubing, a material known for its refined ride quality and excellent strength-to-weight ratio. Whether you’re embarking on a weekend adventure or tackling rugged trails, this frameset is built to deliver exceptional performance and versatility.
The Croix De Fer 12/12 725 Frameset is meticulously engineered to meet the demands of contemporary cycling. Its 725 tubing is mandrel-butted and heat-treated, allowing for thinner walls compared to non-heat-treated steels. This not only reduces the overall weight of the frame but also ensures that it remains sturdy and reliable under pressure. With the Croix De Fer, you’re investing in a frame that promises longevity and resilience, making it an ideal choice for both casual riders and dedicated cyclists.
One of the standout features of this frameset is its compatibility with the latest wheelsets. Equipped with 12mm thru-axles, it accommodates modern wheels while offering improved stability and handling. The frame is designed to support up to a 45mm rear tire and a 50mm front tire on 700c rims, enhancing its all-terrain capabilities. If you prefer experimenting with 650B wheels, you can fit up to a 44mm rear tire and a 50mm front tire, further expanding the frame’s versatility.
In addition to its exceptional tire clearance, the Croix De Fer 12/12 Frameset comes with flat mounts for disc brakes, ensuring reliable stopping power in all weather conditions. The internal rear brake hose routing keeps the bike looking sleek and uncluttered while providing optimal brake performance. The inclusion of a third bottle mount, rack and guard mounts, and fixings for Anything Cages on the forks makes this frame incredibly practical for long-distance touring and bikepacking.
Every detail of the Croix De Fer 12/12 725 Frameset is crafted with the rider’s needs in mind. Its modern design elements, combined with the durability of Reynolds 725 tubing, make it a standout choice for those seeking a reliable and adaptable bicycle frame. Whether you’re upgrading your existing bike or starting a new build, the Croix De Fer offers unbeatable performance and value.
Make the Croix De Fer 12/12 725 Frameset Large your next investment and experience the perfect blend of modern innovation and classic reliability. It’s not just a frame; it’s a gateway to endless cycling adventures.

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.

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 Fix This Bike, you’re choosing a service that prioritises your riding experience, environmental responsibility, and exceptional quality from the moment you receive your bike.
