The Grass Is Greener
The Croix de Fer 40 is the rugged, dependable, yet playful elder brother of the Croix de Fer range. Built around a Reynolds 725 steel frame, paired with a Chromoly thru-axle fork, a modern 1x Shimano GRX drivetrain, and dependable gravel rubber, it’s a true adventure machine.
From 200 km+ endurance days to fast technical loops, mixed on-road/off-road commutes, or a spontaneous evening blast, the Croix de Fer 40 is geared for anything.
Shimano GRX 1×12 Drivetrain
The Croix de Fer 40 features a Shimano GRX 1×12-speed drivetrain, delivering simplicity, reliability, and excellent performance in rough conditions. The single chainring design improves mud clearance and chain retention—perfect when trails get technical.
Beautiful on the Inside
Customisable internal cable routing keeps everything neatly hidden while allowing easy integration of dynamo lighting. The result is a clean, refined look regardless of drivetrain setup.
Drop It Like It’s Hot
The internal routing also makes installing or removing a dropper seatpost quick and hassle-free, no bottom bracket routing required. Add a dropper for technical terrain or remove it for longer adventure rides.
Big Rubber, Big Comfort
Rolling on Maxxis Rambler 45mm tubeless-ready tyres, paired with the Amplitude G100 wheelset featuring a 26mm internal rim width, the Croix de Fer 40 delivers a fast, stable, and comfortable ride across all conditions.
