Specialized Sirrus 3.0 Hybrid Bike
Fun and efficient, the Specialized Sirrus 3.0 Hybrid Bike is a great way to get around town or explore further afield at the weekend. The A1 Premium Aluminium frame and FACT 9r Carbon fork provide a comfortable and smooth ride, with the capacity to add a rack and mudguards further increasing the bike’s utility. Hydraulic disc brakes add all-weather capability, providing power and control even in wet weather, whilst the Specialized RoadSport Reflect tyres are fast-rolling but have enough volume to provide cushioning against poor road surfaces. Reflective sidewalls add low-light safety. Shimano gears make light work of hills with their handlebar-mounted shifters providing intuitive shifting and the Body Geometry finishing kit ensures ride-long comfort.
