Orbea Alma H50 29" Mountain Bike 2021
The perfect hardtail for riders new to MTB, the Orbea Alma H50 29" Mountain Bike is full of features you might expect from a bike with a much higher price tag. The strong but light Hydro Alloy frame is perfect for the job, ensuring a snappy and responsive ride with the durability to last. A RockShox 30 front fork features 100mm of travel to absorb all the bumps, tree roots, and rocks on your local trails.
Change gear quickly and easily using the Shimano Deore M5100 gearset, featuring a wide-ranging 11-speed cassette and 1x chainset for less chance of dropping your chain when the going gets tough. Stop quickly and safely using the Shimano M2100 hydraulic disc brakes, with superb modulation. The 29" Wheels roll nice and fast, with the Maxxis Ikon 2.20" tyres making this a great option for cross country riding too.
