Genesis Croix de Fer 10 Flat Bar Gravel Bike 2026 with Shimano 1x9-Speed Drivetrain and Hydraulic Brakes

The Genesis Croix de Fer 10 Flat Bar 2026 is the most accessible entry point into the Croix de Fer range — a capable, no-nonsense gravel bike built on the same proven steel platform as the rest of the family. Durable, comfortable, and ready for adventure from day one, it's designed for riders who want to get out on gravel, mixed surfaces, and light off-road routes without overcomplicating things. Generous clearance for 700x45c tyres means you can run a wide, confidence-inspiring setup on loose and varied terrain. Available in sizes from X-Small to X-Large, it's a unisex platform designed to fit a wide range of riders.

The Shimano Cues U4000 1x9-speed drivetrain keeps things simple and reliable — a single chainring setup with a wide-range cassette gives you the gearing you need for gravel climbs and open roads without the complexity of a front derailleur. Shimano hydraulic disc brakes deliver consistent, powerful stopping in all conditions, while tubeless-compatible rims and tyres are ready to run sealant to reduce puncture risk on remote routes. The flat bar setup promotes an upright, comfortable riding position with precise handling — ideal for riders who prefer a more relaxed stance or are new to drop bar cycling. Dropper post compatibility adds further versatility for technical terrain when you're ready to explore it.

The Croix de Fer 10 is the starting point of the 2026 Genesis Croix de Fer family. As your riding evolves, the range scales with you — the Croix de Fer 30 2026 steps up to a 2x10-speed drivetrain and drop bar, while the Croix de Fer 40 2026 and Croix de Fer 50 2026 offer full Shimano GRX specifications for more demanding riding.

What It's Good For

• Entry-level gravel riding and mixed-terrain adventure on a durable steel platform
• Riders new to gravel or those who prefer a flat bar for an upright, comfortable riding position
• Simple, reliable 1x9-speed gearing with Shimano Cues U4000 for varied terrain
• Confident all-weather braking with Shimano hydraulic disc brakes
• Reduced puncture risk with tubeless-compatible rims and tyres
• Generous 700x45c tyre clearance for grip and stability on loose surfaces
• Technical terrain adaptability with dropper post compatibility
• Unisex fit across a full size range (X-Small to X-Large)

What It's NOT Good For

• High-speed road racing or competitive events where an aero carbon frame is required
• Riders who prefer a drop bar position — see the Croix de Fer 30 2026 for a drop bar build
• Aggressive full-suspension mountain biking on technical singletrack
• Riders who want a wider gear range — the 1x9-speed setup is capable but narrower than 1x12 or 2x alternatives higher in the range
• Riders prioritising the absolute lightest build — steel frames carry more weight than carbon alternatives

Frequently Asked Questions

What sizes are available?
The Croix de Fer 10 Flat Bar 2026 is available in X-Small, Small, Medium, Large, and X-Large. We recommend checking the Genesis geometry chart or contacting us for a personalised sizing recommendation based on your riding position and inseam.

Is the bike tubeless ready out of the box?
The Croix de Fer 10 comes with tubeless-compatible rims and tyres. You will need to add tubeless valves and sealant to complete the setup — something we can assist with at point of purchase.

Does the bike come with a dropper post fitted?
No — the frame is dropper post compatible but a dropper post is not included as standard. Contact us if you'd like advice on compatible options to add to your build.

Why a flat bar rather than a drop bar?
The flat bar gives an upright, natural riding position that many riders find more comfortable and intuitive, particularly on technical or loose terrain where precise steering control matters. It's also a great choice for riders transitioning from mountain bikes or hybrid bikes to gravel. If you prefer a drop bar, the Croix de Fer 30 2026 is the next step up in the range.

Is this bike suitable for all genders?
Yes — the Croix de Fer 10 uses a unisex geometry designed to work well for all riders across the available size range.
