Orbea Oiz H20 FS Mountain Bike 2023
Orbea's fastest XC bike to date, the Oiz 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 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.
Shimano's MT201 hydraulic disc brakes provide consistent, reliable performance in all conditions, while a Deore drivetrain delivers smooth shifting across the wide ranging cassette. Maxxis' Ikon is a lightweight XC tyre designed for speed, traction and reliability in a range of conditions and terrains. Both the wheels and tyres are tubeless-ready for more grip, greater comfort and fewer punctures.
