Orbea Alma M-LTD 29" Mountain Bike 2021
Precise, responsive and ultra-efficient, the Orbea Alma M-LTD 29" Mountain Bike is the pinnacle of cross-country technology. The super-light OMX carbon construction is perfectly paired with the rigid Orbea Spirit fork and provides an intuitive, almost telepathic ride quality that maximises rider efficiency and power. Designed for their pro-team, but available to you, Orbea's OMX carbon is built for those who demand only the best. Born from the hunt for perfection, advanced manufacturing techniques and top-quality materials ensure that OMX models are the peak of mountain bike performance.
Developed in conjunction with their World Cup cross-country team, the Alma M-LTD geometry provides uncompromising performance through an aggressive, yet comfortable ride position. By focusing on precision, the angles of the frame promote maximum power transfer that is perfect for gaining the edge come race day. With a weight of just 500 grams, the Spirit fork is incredibly lightweight and features a choice of internal or external brake routing for a clean look. Unique rubber fork end protection prevents frame damage in the event of a crash, and the 501mm axle to crown replicates a 100mm suspension fork at 20% sag to keep the geometry responsive.
As the lightest and fastest mountain biking wheel DT Swiss offer, the XRC 1200 Spline® wheelset is a winning combination when paired with the Alma frame. Its carbon construction is lightweight, and the ratchet hub offers instant engagement that excels in a race environment. The full SRAM Eagle AXS wireless groupset provides state-of-the-art shifting performance, with the wide-range 10-50t rainbow cassette delivering a wide, 100% gear range. The SRAM Level Ultimate Carbon disc brakes blend low weight with high power in a sleek, durable design, with a solid feel perfect for late braking.
