Orbea OIZ H20 Mountain Bike 2022
Whether racing XC laps or tackling big mountains, Orbea's OIZ H20 Mountain Bike won’t disappoint.
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 32 Float Rhythm 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 and Deore 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 Maxxis Rekon Race tyres offer an excellent balance between traction and rolling speed. Both the wheels and tyres are tubeless-ready for more grip, greater comfort and fewer punctures.
