Orbea OIZ H10 FS Mountain Bike 2023
Orbea's fastest XC bike to date, the OIZ H20 Mountain Bike won’t disappoint, and it's light at just 1740 grams frame only. Fast and fun on the descents and efficient on the climbs, the OIZ frame is constructed from hydroformed high polished aluminium with a powerspine design that makes it stiff in high stress areas and removes excess material elsewhere.
With 120mm of travel front and rear along with a modern, slack geometry, the OIZ is a match for almost any terrain, yet it never forgets its racing roots so retains an enviable pedalling efficiency that simply means more speed across the ground. A Fox 34 Float SC Performance fork and i-line DPS Performance shock ensure that the suspension is well controlled and highly tuneable with the Alloy Link rear suspension design keeping pedal bob in check.
There can be few arguments about the effectiveness and reliability of Shimano’s XT drivetrain components, and the M6100 hydraulic disc brakes are just as well respected for their reliable performance. A dropper seatpost is in place for use on more challenging sections of trail and the Forekaster are an aggressive XC tyre that rolls fast and accelerates well. Both the wheels and tyres are tubeless-ready for more grip, greater comfort and fewer punctures.
