- RockShox Judy Silver TK fork, 110mm travel

The Orbea Alma H20 is built for riders who want a pure and direct connection with the trail. Its hydroformed aluminium frame uses advanced shaping and manufacturing techniques, giving you a lightweight and efficient platform that feels lively on climbs and stable across rougher ground. For riders who prefer alloy, this is one of the most refined and responsive frames available, designed to deliver dependable performance season after season.
A key feature of the Alma frame is the X-Fader seat tube design, which acts as a small but effective vibration damper. By adding extra vertical compliance, it helps soften repeated trail buzz, improves comfort on longer rides and supports better control when the trail turns rough.
Up front, the bike runs a RockShox Judy Silver TK fork with 110mm travel, a sweet spot for XC riding. It offers enough support for roots, rocks and technical sections while keeping weight sensible for quicker acceleration and efficient climbing. The geometry is tuned around this fork length, giving the bike a balanced feel across technical singletrack and open fire roads.
A Shimano 12-speed drivetrain combines Deore shifters with an XT rear mech for crisp gear changes and long-term reliability. Paired with a wide-range 10–51T cassette and 32T chainring, it offers gearing for steep climbs, fast flats and everything between.
Shimano MT410 hydraulic disc brakes deliver consistent stopping power in all weather conditions, giving you confidence when descending or weaving through tight trail features.
Rolling on 29-inch alloy wheels, the Alma H20 feels quick, smooth and predictable. The Pirelli Scorpion Sport XC tyres provide dependable grip on mixed terrain, adding stability and speed without feeling draggy.
Finishing touches such as the Selle Italia Model X saddle and wide 740mm cockpit help create a comfortable, efficient riding position ready for XC loops, local trails and long off-road sessions.
If you’re after a fast, efficient and confidence-inspiring hardtail for cross-country riding, the Orbea Alma H20 offers great build quality, modern geometry and the everyday reliability that riders appreciate on every ride.
