Orbea Occam H30 Mountain Bike 2021
Blending reactivity with composure thanks to its sophisticated alloy frame, plush suspension and accurate components, the Orbea Occam H30 full suspension mountain bike tackles and conquers any off-road trail scenario with consummate ease.
Light but strong and laterally stiff thanks to its triple-butted, hydroformed alloy composition, the frame acts as dependable, high performing cornerstone to the build. The front and rear triangles of the frame are linked via an asymmetrical configuration that reduces peak loads on the pivots and helps the FOX rear suspension unit to smoothly deliver cushioning across even the most rutted of tracks. Partnering the frame perfectly and affording greater levels of line precision and comfort is the Marzocchi Bomber Z2 fork and its 140mm of progressive suspension. The chassis adheres to Orbea’s Trail Geometry principle that equally donates stability and cornering nimbleness and positions the rider perfectly for power production.
Gear changing duties across a wide ranging cassette are completed with dependability by the Shimano Deore 12-speed set up while the hydraulic disc arrangement bestows powerful and modulated braking in any weather condition. Increased rolling momentum is provided naturally by the 29” Race face AR 30 alloy wheelset that is tough enough for the roughest of terrain. A dropper post crowns the spec sheet by infusing higher levels of confidence when charging down the most technical of routes.
