Orbea Oiz H30 Mountain Bike 2021
The Orbea Oiz H30 Mountain Bike merges a reactive and robust high-grade alloy frame with generous amounts of suspension and an aggressive geometry to deliver any rider across even the most demanding cross country terrain with energy and enthusiasm.
Both front and rear frame triangles utilise the high-grade hydroformed aluminium for their construction and this, along with its internal butted format, infuses a responsive ride characteristic and off-road robustness. Linking these two frame constituents is the UFO suspension design that has a clean appearance and aids the FOX rear dampening unit in promoting plush and composed amounts of travel. The frame has a nimble character and positions the rider ideally for efficient power transfer thanks to its XC-racing inspired geometry. The frame is partnered by the FOX 32 Float SC Rhythm fork that smooths the most rutted of trails with its 120mm of progressive cushioning.
29” Orbea OC1 alloy wheels manage the biggest of obstacles and impacts with heightened levels of momentum while the Shimano Deore gear setup enables any topography to be conquered thanks to its wide range of ratios and slick shifting. Any downhill, no matter how fast or technical, is handled with aplomb by the powerful and highly precise hydraulic disc brakes that work flawlessly even in the muddiest of riding conditions.
- 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 a 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 32 Float SC Rhythm 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 gear configuration changes without fault and is durable
- Shimano hydraulic disc brakes are powerful and modulated regardless of riding conditions
