Built around 120mm of race-tuned suspension front and rear, the Oiz offers impressive grip and control without sacrificing speed. The RockShox Reba fork with DebonAir+ spring provides a supple initial feel and consistent support, while the Fox Float SL Performance rear shock is custom tuned for the frame and features a remote push-lock, allowing quick adjustments for climbs or sprints.
Modern XC geometry gives the Oiz a confident, planted feel on technical descents while remaining sharp and responsive when climbing. Orbea has carefully balanced stiffness and compliance, ensuring the frame tracks the ground effectively rather than feeling harsh, helping maintain momentum over roots, rocks and rough trail sections.
The Shimano Deore 12-speed drivetrain offers reliable shifting and a wide 11–51t gear range, making steep climbs more manageable while maintaining efficiency on faster sections. Shimano MT201 hydraulic disc brakes provide consistent, easy-to-control stopping power, ideal for long rides and varied conditions.
Rolling on 29” wheels with tubeless-ready alloy rims, the Oiz H30 delivers strong rollover ability and traction on modern XC courses. A dropper seatpost comes fitted as standard, adding extra confidence and control when the trail points downhill.

* Mountain bikes are sized differently to road bikes. Typically, they are sized in inches as the first MTBs were produced in the USA. European brands like Lapierre and Haibike like to use centimetres for all their bikes. The measurements of their mountain bikes doesn’t match their road bikes but are like a simple conversion from the inches measurement. This is why we have included cm measurements in brackets for the Mountain bike column.
Read our bike size guide for more information on sizing.
