Up front, the Future Shock 3.2 suspension system provides 20mm of adjustable travel above the head tube. This innovative design absorbs bumps and vibrations, keeping your upper body fresher on long rides while maintaining pedalling efficiency and precise steering. Paired with a FACT carbon fork, it ensures stable handling and comfort on everything from gravel descents to rough tarmac.

The drivetrain is powered by Shimano’s GRX Di2 RX825 groupset, a fully electronic 1x12-speed system optimised for gravel. With wireless shifting at your fingertips, you get lightning-fast gear changes and smooth reliability in all conditions. The RX827 rear mech paired with a 10-51T XT cassette and GRX RX820 chain set provides the wide range you need for steep climbs, fast flats, and loaded adventures.

Braking performance is handled by Shimano GRX hydraulic discs, delivering powerful, consistent stopping across all terrain and weather. This gives you total confidence to descend aggressively and maintain control when conditions are unpredictable.

The bike rolls on Roval Terra C carbon wheels, with a 25mm internal rim width and 32mm depth, designed for strength, stability, and tubeless compatibility. Paired with Tracer 700x45c tyres, you get a fast-rolling setup with versatile grip for mixed-surface riding.

A standout feature is the SWAT 4.0 internal storage system, built into the down tube to provide secure, easily accessible space for tools, spares, or nutrition. This clever integration frees up your jersey pockets and keeps the bike neatly organised for long rides or races.

Finishing touches include a Roval Terra carbon seat post for added compliance, a Specialized Adventure Gear Hover bar with 12° flare for off-road control, and a Body Geometry Power Expert saddle designed for comfort and efficiency on long days in the saddle.
