Specialized Sirrus 2.0 Step-Through Hybrid Bike
Intended for use about town and beyond, the Specialized Sirrus 2.0 Step-Through Hybrid Bike offers a lightweight A1 Premium Aluminium frame complete with mudguard and rack mounts for all-weather use and a lowered top tube for greater confidence. The 8-speed Shimano drivetrain has double front chainrings for a wider range of gears and handlebar-mounted trigger shifters for ease of use whilst maintaining control of the bike. The Promax F1 hydraulic disc brakes are also very easy to use and provide great stopping power even when wet. The fast-rolling Specialized RoadSport tyres are wide enough for increased comfort and grip without adding any drag and feature a reflective sidewall for increased visibility at night.
