Orbea Occam H20 Mountain Bike 2021
With a refined alloy frame, a balanced geometry and highly respected components, the Orbea Occam H20 full suspension mountain bike imparts a lofty level of performance and an energetic character when confronting any trail terrain, whether it be fast and bumpy or tight and technical.
Efficiency of power transfer and low weight is achieved by the frame thanks to its high-grade, hydroformed alloy construction that possesses a triple-butted internal tube format. Increased trail adhesion is granted by the asymmetrical design that links the front and rear triangles to reduce peak loads and aid the FOX suspension unit in giving plush and controlled levels of cushioning. Complementing the frame is the FOX 34 Float Performance fork that levels the ruts, rocks and roots to heighten trail composure and line accuracy. The frame and fork are blended together with a perfectly poised geometry that raises stability, cornering prowess and power transfer in equal measures.
29” Race Face AR 30 wheels roll with fluidity, no matter the obstacles being encountered, accelerate sharply under power and are hardy enough for the roughest of tracks. The hydraulic disc configuration bestows accurate and powerful braking in any off-road conditions while the Shimano XT 12-speed setup guarantees slick and dependable gear changes.
To complete the build, the dropper post gives the rider confidence-inspiring amounts of balance when flying down twisty descents and is remotely controlled for added convenience.
