Orbea’s Oiz 29" H30 Mountain Bike brings the XC race-winning success of the carbon model to a wider audience by using carefully sculpted, hydroformed alloy for the frame instead. The geometry follows that of the longer travel TR versions, with 120mm of suspension front and rear whilst retaining all the XC efficiency that the Oiz is renowned for. Both the shock units feature remote lockouts and there is internal routing for the gear cables protecting them from mud and grit. The configuration of the front triangle leaves enough room for two water bottles, so hydration on longer rides or races isn’t a problem.
As befits its cross-country heritage, 29” wheels and fast, light 2.2” Maxxis Ikon tyres are fitted, ensuring speed across any terrain. Both wheels and tyres are tubeless-ready, making the conversion simpler for the extra benefits of a set up without inner tubes. Shimano’s Deore M6100 groupset is well-loved for its excellent, no-nonsense performance and reliability, with the 12-speed 10-51t cassette offering a very wide range of gears. Equally impressive are the hydraulic disc brakes for modulated control and excellent stopping power.
