Orbea Alma H20 Mountain Bike 2022
Fast and efficient over a range of terrain, the Orbea Alma H20 Mountain Bike is the perfect choice for rapid singletrack and gruelling climbs, with its cross country bloodline ensuring excellent efficiency on the trail. A Suntour RAIDON 32 fork offers compliance over rough surfaces and remains lightweight to retain a spritely ride feel. Powerful hydraulic disc brakes boost control when descending and offer excellent bite in wet weather conditions.
The hydroformed frame is lightweight and responsive, making it a perfect upgrade platform for those looking to push their riding to the limits. A 12-speed Shimano drivetrain provides crisp and reliable shifting, with much of the performance found on the higher-end units, and grippy Maxxis tyres deliver confidence on hardpack terrain.
