Orbea Occam H30 Mountain Bike 2020
The Orbea Occam H30 Mountain Bike incorporates Trail geometry into a full-suspension, 140mm travel frameset for versatile performance. Efficient at climbing, providing control and stability on technical descents, and able to excel across a wide range of terrains, this bike pairs a strong, stiff 140mm aluminium frame with a Marzzocchi Bomber Z2 fork, with the front and rear travel offering smooth shock-absorbing suspension.
Shimano SLX is a great complement to this bike's credentials, with the 1x12-speed setup marrying a wide-ranging 11-51t cassette to a 32-tooth chainring, and hydraulic discs providing all-weather stopping power. Mach1 Maxx wheels can be setup in a tubeless configuration if preferred and, fitted with Maxxis High Roller 2.50" 29er tyres, will roll incredibly fast, swallowing up obstacles in their path. With the inclusion of a dropper post, you can quickly move your saddle down and out of the way for improved manoeuvrability on steep drops and long downhill sections.
