The Orbea Oiz is a dedicated cross-country race bike that fully commits to a 120mm suspension platform. Rather than stretching a shorter-travel frame to handle modern, highly technical race courses, Orbea redesigned the Oiz from the ground up around the longer travel. The result is a purebred racing machine that prioritizes pedaling efficiency and forward momentum over casual trail comfort.
Available in both carbon and hydroformed aluminum frames, the current generation utilizes a single-pivot flex-stay suspension layout paired with a proprietary three-position remote. It is built for aggressive cross-country racers and marathon riders who want a firm, highly responsive chassis that can still absorb the punishing impacts of modern race tracks. While the increased travel broadens its capability on rough descents, the Oiz remains strictly focused on speed, rewarding riders who actively weight the front end and push hard on the pedals.

Geometry & fit.
4 sizes published.
The Oiz features a modernized cross-country geometry that balances high-speed stability with sharp, low-speed maneuverability. By slackening the head tube to 67 degrees and extending the reach, Orbea has centered the rider between the wheels, providing a calm and stable steering feel on steep descents. To maintain agility, the chainstays are kept short—measuring 432mm on carbon frames and slightly longer on the aluminum models—which helps the bike change direction quickly in tight singletrack.
Rider posture is decidedly aggressive. A steep 76.5-degree seat tube angle positions the hips directly over the bottom bracket, optimizing power transfer and keeping the front wheel planted on severe inclines. The front end is kept low with a minimal stack height and a negative-rise stem, pulling the rider's weight forward. While this stretched, aerodynamic stance is ideal for racing, less conditioned riders may experience hand or lower back fatigue on longer marathon stages. To mitigate this, the cockpit can be adjusted with standard spacers, though the integrated cable routing complicates stem swaps.
Where the handlebar sits relative to the bottom bracket — the single most important fit pair.

The lineup.
10 builds, ranging $2,599 – $10,499.
The Oiz lineup spans a wide price range, split across three frame materials: hydroformed aluminum, mid-tier OMR carbon, and the flagship OMX carbon. The aluminum models offer an accessible entry point, utilizing the same suspension layout and geometry as the carbon frames, albeit with a weight penalty.
The carbon range begins with the OMR frame, which carries a slight weight increase over the top-tier version but retains identical stiffness and geometry. Mid-range builds like the M10 hit a distinct sweet spot for value, pairing the OMR frame with Fox Factory suspension and Shimano XT components to deliver elite-level performance without the premium price tag of the flagship models.
At the top of the ladder, the OMX carbon frame sheds additional weight and switches to a flat-mount rear brake. These premium builds feature high-end wireless drivetrains from SRAM or top-tier Shimano XTR groupsets, alongside Orbea’s lightweight Oquo carbon wheelsets. Across the carbon lineup, Orbea’s MyO program allows buyers to customize paint colors and swap select components, such as dropper post lengths or tires, directly from the factory.
From the press.
15 reviews from the cycling press.
Reviewers consistently praise the Oiz for its exceptional climbing speed and firm pedaling platform. The high anti-squat kinematics create a highly efficient ride that translates power directly into forward momentum. Testers found it to be a "snappy pedaler" (Pinkbike), noting that the bike accelerates rapidly out of corners and maintains speed effortlessly on flat singletrack. The three-position Squidlock remote is frequently highlighted as a major asset, particularly the medium setting, which firms up the rear shock for technical climbs while leaving the fork open to track over roots and rocks.
On descents, the suspension provides a valuable safety net, but testers emphasize that the bike retains a firm, race-focused character. The rear shock requires a strong push to initiate, meaning it transmits more trail feedback than a dedicated trail bike. Under heavy braking in rough terrain, the rear wheel can occasionally be caught "skipping about" (BikeRadar), requiring precise line choices.
Ergonomics and maintenance drew the most criticism. Multiple reviewers reported their "calves brushing against them" (Road.cc) due to the wide seatstays, which could cause discomfort depending on a rider's pedaling stance. Additionally, the headset cable routing was widely panned by mechanics, and several testers found the vertical orientation of the dropper lever on the Squidlock remote awkward to actuate during hard efforts.
