Orbea MX 40 Mountain Bike 2021
Get into the wonderful world of cross country and trail riding without breaking the bank, with the Orbea MX 40 Mountain Bike. Built on a strong and reliable alloy frame, this is a durable machine with a competitive specification to match. To soften bumps and jolts, the SR Suntour XCT fork features 100mm of suspension. For extra versatility, the frame comes with mounting points for you to add a rear rack (sold separately) and make the most of longer tours on two wheels.
Shimano's Alivio shifting system features an easily operated 9-speed setup with a double chainset to provide a wide range of gears that allow you to tackle any terrain. The inclusion of hydraulic disc brakes is a real head-turner and elevates this bike above plenty of competitors. With the Shimano MT200 brakes, you can stop with great control and modulation in any weather. There's superb grip from the Kenda K1153, allowing for great traction on loose surfaces.
