Orbea Occam H20 LT FS Mountain Bike 2023
With 150mm of plush suspension travel, the Orbea Occam H20 LT FS Mountain Bike splits the difference between the standard Occam and hell-raising Rallon models, delivering on-trail efficiency with the ability to charge steep, gnarly singletrack. The differences don’t end there though, a FOX 36 Float Performance fork provides unmatched levels of adjustment and sublime stiffness, and the Fox FLOAT X Performance rear shock is supremely supple for traction on rough terrain.
Stiff, lightweight and durable, and with just a slight weight penalty compared to the carbon equivalent, the hydro high polished triple butted aluminium frame features an asymmetric design to enhance rigidity and retain an uninterrupted seat tube, allowing for the fitment of long-travel dropper seatposts. 29” wheels are the new standard in speed and grip, with the Maxxis tyres delivering claw-like traction, even on loose surfaces. The updated two-piece linkage further improves stiffness by removing unnecessary parts and can house a unique 4-bit multi-tool (purchased separately) to help with mechanicals on the trail.
An Orbea OC Mountain Control handlebar deals precise control whilst minimising fatigue and is paired with a short stem to keep your weight centred on the bike. The Race Face AR wheels are durable and feature fast pickup for rapid acceleration. A Shimano SLX drivetrain provides 12-speed performance in a lightweight and tactile package, while Shimano hydraulic discs deliver premium braking performance.
