Mondraker Arid Alloy Frame – Built for Gravel Adventures
The Mondraker Arid S features an aluminium gravel frame developed to offer a balance of strength, riding efficiency and comfort over a wide variety of terrain.
Inspired by the design of Mondraker's premium carbon gravel bikes, the Arid alloy frame retains distinctive details including the unique seatstay design and clean, modern lines.
HHG internal cable routing keeps cables neatly integrated, while a threaded T47 bottom bracket, 12x142mm rear thru-axle and flat-mount brake compatibility provide a practical foundation for long-term use.
With multiple mounting points for accessories, the Arid S is well suited to riders who want to carry extra equipment for longer days and gravel adventures.
Stealth Air Carbon Fork – Lightweight and Responsive
Up front, the Mondraker Arid S uses a Stealth Air Carbon gravel fork with a tapered steerer and integrated flat-mount brake compatibility.
The carbon construction helps keep weight down while providing precise handling and a responsive steering feel.
Combined with the gravel-specific frame geometry, the fork contributes to a balanced ride on roads, forest tracks, gravel paths and mixed off-road surfaces.
Shimano GRX 12-Speed – Reliable Gravel Gearing
The Arid S is equipped with a Shimano GRX RX822 12-speed rear derailleur and Shimano GRX RX610 controls, delivering reliable mechanical shifting designed for gravel riding.
A 40T front chainring and Shimano SLX 10-45T cassette provide a useful range of gearing for rolling roads, gravel climbs and mixed-terrain adventures.
The simple 1x drivetrain removes the need for a front derailleur, making gear selection straightforward while reducing drivetrain complexity.
From steady road miles to rough gravel climbs, the Shimano GRX drivetrain offers dependable shifting for riders who want to explore different surfaces without changing bikes.
Shimano GRX Hydraulic Disc Brakes
The Mondraker Arid S features Shimano GRX RX610 hydraulic brake controls with Shimano RX400 calipers and 160mm Shimano CL800 Ice-Tech rotors.
Hydraulic disc braking provides controlled, consistent stopping power across wet roads, loose gravel, muddy tracks and longer descents.
The GRX controls are designed for drop-bar gravel riding, providing convenient braking and gear shifting from the riding position.
Mavic Allroad Wheels and Maxxis Reaver Gravel Tyres
The Arid S comes equipped with Mavic Allroad Disc UST wheels, featuring a 25mm internal rim width and tubeless-ready construction.
These are matched with Maxxis Reaver 700x45 tyres, designed to provide a balance of rolling speed, traction and control on gravel and mixed terrain.
The Reaver tyres feature a dual-compound construction, EXO sidewall protection and a 120 TPI casing, making them well suited to fast gravel routes and longer rides.
Both wheels and tyres are tubeless ready, allowing the bike to be converted to a tubeless setup with the appropriate valves, sealant and preparation.

Gravel Geometry – Confidence Beyond the Road
The Mondraker Arid S uses progressive gravel-specific geometry, combining a stable wheelbase with responsive steering and a comfortable riding position.
A 70-degree head angle and 425mm chainstays provide a balance of stable handling and manoeuvrability across different terrain.
The flared Onoff S3 GR handlebars feature a 16-degree flare, offering additional hand clearance and control when riding in the drops on rough surfaces.
Whether you're riding fast gravel routes, long-distance mixed-terrain loops or weekend adventures, the Arid S delivers an engaging and confident riding experience.
