Specialized Rockhopper Expert 1X Mountain Bike 2020
The Specialized Rockhopper Expert 1x Mountain Bike is a classic hardtail that's ready and waiting to make those singletrack dreams a reality. The lightweight A1 SL Aluminium frame is tight and nimble, using tube shapes that save weight whilst still ensuring comfort and handling are maintained. Cables are run internally as well, giving a sharp look to match its snappy capability. The unique Sport XC 29 geometry puts the rider into an optimum position for control when riding at speed, comfort when riding all day and agility when riding twisty trails. The frame is paired with Shimano MT200 hydraulic brakes for powerful braking and a 1X Shimano Deore drivetrain that uses a 30T chainring and 11-42t cassette offering a huge range that will deliver the right gear for any situation.
At the front an SR SunTour XCR-Air 29 suspension fork has an adjustable rebound so that you can fine-tune the feel to suit your ride style. The 29er wheels will float over small trail obstacles, carrying momentum into climbs and the 2.3" tyres have a huge amount of traction in corners.
Features

- Shimano's reliable MT200 hydraulic disc brakes
- Air-sprung SR SunTour XCR-Air 29 suspension fork
- Clutch rear derailleur that keeps the chain properly tensioned all the time for faster, quieter shifts
