Orbea Occam H20 Mountain Bike 2020
Lively and capable, the Orbea Occam H20 Mountain Bike features a hydroformed 140mm travel aluminium frame with Trail geometry, full suspension and smooth tube to tube transitions to craft a versatile bike with impressive looks. Nimble up climbs and stable whilst descending, this is a do-everything bike with a FOX 34 Float Performance 140mm travel fork that eats up bumps and dampens shocks. The innovative single-sided strut serves to alleviate suspension forces from a critical high-stress area whilst leaving space for a bottle accessed from the left side. Utilise the telescopic Orbea OC2 Dropper seatpost on tricky descents, sweeping turns and more.
Sharp shifting is a given with Shimano SLX and XT components, with the 1x12-speed setup ensuring all bases are covered when it comes to selecting the right gear for the toughest gradients. The single 32t chainring makes for simple maintenance, whilst hydraulic disc brakes provide sure stopping power regardless of conditions. Rapid-rolling 29" Maxxis tyres feature chunky tread to glide over obstacles and improve traction, and are paired with Mach1 Maxx wheels which can be run tubeless if desired.
