Orbea OIZ H30 Mountain Bike 2022
The Orbea OIZ H30 Mountain Bike is a cross-country workhorse that balances value and performance to deliver a ride quality that punches well above its price bracket. The hydroformed frame features aggressive and responsive geometry, making it an ideal race bike for riders on a budget. Sleek in its appearance, the polished welds mimic the smooth aesthetic found on the carbon equivalent, while the 120mm of rear suspension is controlled by an Alloylink linkage design.
12-speeds are offered by the Shimano Deore drivetrain, which sees much trickle-down technology from the brand’s higher-end groupsets. FOX suspension irons out the trail and features a remote lockout to increase efficiency on long, unforgiving climbs. Orbea in-house wheels offer reliable performance, and Maxxis Ikon tyres issue sublime grip on fast, hardpack terrain.
- The OIZ is designed for fast, experienced riders who demand a lightweight 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 32 Float Rhythm fork uses an open bath damper to control its 120mm of smooth, supple travel
- Fast-rolling 29" Orbea OC1 25c alloy wheels are stiff, strong and light
- Shimano Deore offers 12-speed performance without the associated price tag
- Shimano hydraulic disc brakes are powerful and offer excellent modulation, regardless of riding conditions
