Orbea Oiz M30 Mountain Bike 2021
Excelling within any cross country riding scenario thanks to its racing-inspired design and accurate components, the Orbea Oiz M30 Mountain Bike delivers even the most experienced riders to the finish line with increased speed and heightened composure.
The OMR carbon main frame is light and responsive and is complemented by the stiff and efficient alloy rear triangle. These two frame parts are joined by the refined UFO suspension design that saves weight by reducing pivot points and combines with the FOX damping unit to infuse a progressive shock rate for heightened rear wheel traction. Line accuracy is improved by the plush suspension afforded by the FOX 32 Float SC Factory Performance while an aggressive, race-inspired frameset geometry gives sharp handling and a perfect riding position for efficient power transfer.
DT Swiss X-1900 wheels use their 29” alloy rims to grant acceleration and robustness and roll with heightened momentum over even the most irregular of surfaces. A Shimano Deore and XT gear partnership changes across its ratios with smooth actuation and hydraulic disc brakes, also from Shimano, stop with power and modulation no matter the trail conditions.
