Orbea Oiz H20 Mountain Bike 2021
A quick and versatile steed, the Orbea Oiz H20 Mountain Bike performs with accuracy and enthusiasm across any race course or technical trail thanks to its amalgamation of advanced frame design, spritely cross country character and generous levels of suspension.
A high-grade of hydroformed aluminium with a butted construction promotes strength and responsiveness into both the front and rear frame triangles. These triangles are linked via Orbea’s svelte UFO suspension design that has a clean aesthetic and helps the FOX damping unit in infusing increased line adhesion across even the most challenging off-road surfaces. The frame possesses an XC racing-inspired geometry that is lively and encourages the highest level of power transfer while the FOX 34 Float SC Performance fork absorbs even the biggest of hits to increase line accuracy and composure.
Orbea OC1 29” alloy wheels accelerate sharply and preserve momentum across obstacle-strewn tracks and are propelled by the precise Shimano Deore and XT drivetrain partnership. Stopping duties are catered for by the hydraulic disc brake configuration, also from Shimano, that inspires any rider with confidence, no matter the conditions, thanks to its highly refined actuation.
- The Oiz is designed for fast, experienced riders who demand a light and efficient full suspension bike for technical XC courses and high-performance cross country riding
- A stiff and robust hydroformed, butted and smooth welded alloy frame gives an efficient and responsive ride and svelte silhouette
- UFO rear suspension design reduces pivot points and combines with the innovative alloy linkage pattern to deliver lateral stiffness and a composed action
- FOX i-line DPS Performance rear shock with 120mm of suspension progressively manages even the largest of impacts
- FOX 34 Float SC Performance fork increases line accuracy and control with its 120mm of metered travel
- World Cup Geometry is aggressive and precise for maximum power transfer and rapid handling
- Orbea OC1 25c alloy wheels are stiff, strong and light
- Shimano Deore and XT gear configuration changes without fault and is durable
- Shimano hydraulic disc brakes are powerful and modulated regardless of riding conditions
