Orbea Oiz M20

Starting at



Take control. Don't accept compromises. Oiz isn't down-country or trail; this is a 120mm XC race machine that looks as good as it rides. Modern geometry and clever suspension, designed from the start around 120mm, bring extra fun to every ride without compromising weight or efficiency. Simply put, Oiz is the fastest XC bike to leave Orbea's factory in over 180 years.

Removing anything which is superfluous and only adding features that enhance the ride means that at 1740g Oiz is one of the lightest XC frames out there. Lightweight is key for a fast XC bike and relentlessly pursuing the simplest solutions means Oiz doesn’t need to compromise anywhere else to achieve this.


Modern XC racing is more demanding than ever, meaning that modern XC bikes are evolving to offer more control, and fun, on the descents. Orbea's No Compromise Geometry takes feedback from our racers, riders, and tests to make the Oiz Orbea's most exhilarating XC bike.


A steep seat tube and lower stack puts you in the driving seat, in full control of your ride. The longer reach, designed around a 60-90mm stem, offers stability on the descents while maintaining a weighted front wheel for attacking on the climbs and corners.


Frame rigidity is critical for power transmission, however, it is possible to have a frame that is too stiff to track the terrain efficiently. By manipulating the frame materials, optimizing tube profiles, and oversizing bearings that can tightly control rigidity without compromising weight. The result is a frame that is balanced and controlled without sacrificing efficiency.


  • SLACKER HEAD ANGLE: More control and confidence on high speed descents.
  • LONGER TOP-TUBE: Designed around a 60-90mm stem to balance stability with that responsive steering XC racers demand.
  • LOWER STACK: Optimized for a 120mm fork to keep weight on the front wheel for turning and climbing.
  • SHORT CHAINSTAYS: Agile and responsive handling and improved acceleration.
