Orbea Oiz H10 TR Mountain Bike 2021
With its robust and responsive high-grade aluminium frame, XC racing-inspired character and generous amounts of suspension, the Orbea Oiz H10 TR Mountain Bike promotes speed and increased composure across any cross country course and the most challenging trails.
The front and rear frame triangles are formed from a lofty grade of hydroformed aluminium that has a butted construction to increase efficiency and strength. An uncluttered UFO rear suspension design links the two frame components and works in unison with the FOX damping unit in taming any surface irregularity to increase traction and control. Aggressive frame geometry is nimble through the corners and encourages a powerful peddling action while the FOX 34 Float SC Performance fork helps to tidy obstacle-strewn trail lines thanks to its 120mm of plush and progressive travel.
Race Face AR 30c wheels have resilient alloy rims that possess a 29” circumference to grant smooth passage across the roughest of landscapes. These wheels are driven by the unfaltering and precise Shimano XT drivetrain and are stopped in any weather conditions by the highly modulated hydraulic disc brakes. A dropper post is added to the build to help the rider comfortably navigate the quickest and most technical descents with heightened control.
- The Oiz TR takes a thoroughbred XC racing platform and adds bigger suspension, front and rear to create a super-fast and nimble character that is set to conquer any trail
- 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
- The geometry is aggressive and precise for maximum power transfer and rapid handling
- Race Face AR 30c alloy wheels are stiff, strong and light
- Shimano XT gears change without fault and are durable
- Shimano XT hydraulic disc brakes are powerful and modulated regardless of riding conditions
- A dropper post is added to aid control on the most technical downhill sections
