The Orbea Alma M20 is designed to maximise efficiency and speed without losing the control needed for modern cross-country riding. Its lightweight carbon frame balances stiffness and compliance to deliver quick acceleration and responsive handling, while Orbea’s X-Fader design helps reduce trail vibration and rider fatigue over longer distances.
Attention to detail plays a big role in the Alma’s ride quality and usability. Internal cable routing keeps the bike looking clean and reduces clutter around the cockpit, while the integrated frame service window makes maintenance simpler. Orbea’s Smart Clip system also allows full insertion of the dropper post while keeping bottle cage mounting practical and tidy.
A Fox 34 Float SL Performance fork with 110mm of travel adds extra confidence when trails become rough or technical. The remote push-to-lock function lets you quickly firm up the suspension for climbs and smoother terrain, helping maintain efficiency during races and fast-paced rides.
Shimano XT 12-speed shifting delivers crisp gear changes with a huge range for steep climbs and rapid descents alike. Shimano hydraulic disc brakes offer dependable braking control in mixed conditions, while the OQUO wheelset and tubeless-ready Pirelli Scorpion Sport XC tyres balance low rolling resistance with dependable grip and comfort on technical terrain.
The included OC MP10 dropper post gives full control over saddle height adjustment, helping improve confidence on descents and technical sections without adding unnecessary weight. Altogether, the Alma M20 is a capable XC hardtail that feels quick, direct and ready for everything from marathon events to fast local trail loops.
