Specialized Sirrus X 2.0 Step Through Disc Hybrid Bike
The Specialized Sirrus X 2.0 Step-Through Disc Hybrid Bike has been designed by Specialized to make taking the bike the easy option. The lightweight A1 Premium Aluminium frame with internal cable routing and Plug + Play mounts for a rack or mudguard also features step-through geometry to increase confidence and make mounting and dismounting straightforward.
The bike benefits from Promax F1 hydraulic disc brakes for great stopping power with a light action, and large volume Pathfinder Sport tyres for comfort, grip and the ability to head off the tarmac and explore alternative tracks and trails. The MicroSHIFT Advent 8-speed drivetrain has a wide-range cassette and a single front ring that combines the simplicity of operation with plenty of ratios, making selecting the right gear an easy task.
Highlights
- A1 Premium Aluminium frame with step-through geometry and Plug + Play rack/mudguard mounts
