Orbea MX 30 Mountain Bike 2021
A versatile off-road companion, the Orbea MX 30 Mountain Bike features a light but strong alloy frame and front suspension for damping bumps to smooth out your ride. The perfect bike for some off-road cross-country explorations, or undulating trails, the hardtail ensures great power transfer through the rear wheel without rear suspension to absorb any of your effort when riding uphill. The frame has rear rack mounting points, so you could easily carry luggage for longer distance adventures, or turn it into a canal towpath commuter.
With Shimano components, you get unrivalled reliability, and the Deore M4100 series gearset shifts seamlessly. There's a huge range of gearing thanks to the 10-speed cassette and double chainset, so you can tackle any gradient with confidence. Stopping is made easy by the powerful hydraulic disc brakes, which are perfect for off-road conditions too. Rolling on a set of size-specific Orbea Black Rock wheels, the bike handles consistently whether you ride a Small or Medium with 27.5" wheels or any of the larger sized frames with 29" wheels.
