Recap
Mjolnir steel platform with Shimano CUES 2×9 drivetrain and TRP Spyre mechanical disc brakes, built around a quick-release configuration.
The CUES system introduces a logic focused on durability and continuity of operation, while the overall build prioritises simplicity, reliability, and regular use on mixed routes.
Positioning and use logic
The Croix de Fer 10 is the entry point into the Croix de Fer range, retaining the same platform logic but with a more essential build specification.
It is a bike designed for:
Daily use
Non-technical mixed routes
Simple and predictable management
The presence of the Mjolnir frame clearly defines the model: it is not a “basic” bike in behaviour, but a steel platform designed to last and perform over time.
The build reduces complexity without changing the bike’s intended use.
Frame and platform
The Genesis Mjolnir chromoly frame delivers an elastic and progressive ride response, with stable behaviour on both tarmac and dirt.
Compared with Reynolds 725:
Slightly less refined in ride response
But fully coherent for real-world and continuous use
The chromoly fork maintains structural consistency and durability.
The choice of QR axles (100/135 mm) fits into a logic of:
Simplicity
Compatibility
Ease of maintenance
The platform retains:
Internal cable routing
Dropper post compatibility
Full accessory provision
Structurally, the logic is the same as the higher-spec versions.
Build and technical choices
The Shimano CUES 2×9 drivetrain (46/32T – 11-36T) is designed to offer:
Full gear range
Consistent operation
Low maintenance
The CUES system introduces a philosophy focused on:
Longer drivetrain life
Wear resistance
Continuous use
The TRP Spyre dual-piston brakes are a precise technical choice:
Independent pad adjustment
Simple maintenance
Predictable behaviour
The Amplitude G100 wheels with 26 mm internal rim width support wide tyres without instability, maintaining consistency with the rest of the range.
Wheels and tyres / compatibility
Equipped with Maxxis Rambler 700x45 mm tubeless-ready tyres on pre-taped rims with valves included.
Configuration oriented toward:
Use on tarmac and light dirt
Comfort over long distances
Stability on variable surfaces
Tyre clearance up to 47 mm.
When it makes sense

When it does NOT make sense
It is not suitable for sportive or performance-focused use.
