Specialized Sirrus 2.0 Step Through Hybrid Bike
Aiming to make travelling by bike fun and convenient, the Specialized Sirrus 2.0 Step Through Hybrid Bike is great for weekday errands and weekend exploring. The step through frame instils extra confidence thanks to its low top tube design, making mounting, dismounting and stopping at junctions easier. Equally confidence-inspiring is the hydraulic disc brakes, which provide great stopping power in all weather conditions.
Shimano’s 8-speed Acera groupset offers quick, intuitive shifting between the gears and has a wide range of ratios to cope with hills and flat roads alike. The inclusion of Plug + Play rack/mudguard mounts means that the bike can be easily equipped for year-round duties and the reflective strips on the tyres’ sidewalls add extra visibility to traffic approaching from side roads.
Highlights
- Specialized A1 Premium Aluminium frame with Fitness Geometry and Plug + Play rack/mudguard mounts
- Promax F1 hydraulic disc brakes
- Shimano Altus, 8-speed double groupset
- Specialized RoadSport Reflect 700x32c tyres
