Orbea Oiz M PRO Mountain Bike 2021
Blending a top of the range full carbon frame and high-level components with a precise character, the Orbea Oiz M PRO Mountain Bike delivers experienced riders across race courses and technical cross-country topography with increased velocity and enthusiasm.
Orbea’s loftiest grade of carbon comprises the front and rear triangles of the frame to grant a low weight and tremendous levels of stiffness. A lightweight UFO rear suspension configuration teams up with an innovative linkage system to join the front and rear frame components, and these assist the FOX damping unit in heightening traction and control across the roughest of surfaces. Greater line accuracy is added to the mix by the FOX 32 Float SC Factory fork and its plush 100mm of suspension. An aggressive World Cup racing-inspired geometry links the frame and forks and naturally infuses nimble handling characteristics and places the rider perfectly for a powerful pedal stroke.
DT Swiss XR-1650 Spline wheels use their light but strong alloy rims and their larger 29” circumference to roll across any obstacles with consummate ease. They are propelled forward by the impeccable Shimano XT and XTR gear amalgamation and are stopped with powerful and modulated Shimano hydraulic disc brakes, no matter the course conditions.
Highlights
- The Oiz is designed for fast, experienced riders who demand a super light and efficient full suspension bike for technical XC courses and high-performance cross country riding

- World Cup Geometry is aggressive and precise for maximum power transfer and rapid handling
- DT Swiss XR-1650 Spline 25c 29” alloy wheels are stiff, strong and light
- Shimano XT/XTR gear partnership changes without fault and are durable
