Orbea MX ENT 40 Mountain Bike 2021
The sweeping top tube design of the Orbea MX ENT 40 Mountain Bike makes it easy to mount and step down from the saddle. This is a wonderful introduction to cross country and trail riding, with a reliable specification of components. While riding the bike, you'll enjoy plush front suspension thanks to the SR Suntour XCT 30 Coil fork, which softens off-road bumps as well as any cobbles or potholes you might encounter on your way to the wilderness.
The 9-speed Shimano gearset provides all the options you need for steep hills or fast flatter sections. Something you don't usually find at this price point, are the superb Shimano MT200 hydraulic disc brakes, which allow for excellent modulation and stopping power. Rolling on a set of Orbea Black Rock wheels, the Kenda K1153 tyres provide great traction on a mixture of loose and hard-packed surfaces.
Highlights
- Light and durable Orbea Alloy frame
- SR Suntour fork with 80-100mm of plush suspension (size dependant)
- Powerful Shimano MT200 hydraulic disc brakes
- Shimano 9-speed gearset
- Mounting points for rear rack and mudguards
- Grippy 2.35" Kenda tyres for great off-road traction
