Specialized Sirrus Hybrid Bike 2017
The Specialized Sirrus Hybrid Bike 2017 has been specifically designed to provide you with a fun, fast and reliable ride.
The resilience and comfort stem from the A1 Premium Aluminium frame and sturdy steel fork combination. Designed with Specialized's Fitness Geometry, this frameset puts you in a more upright riding position.
As your commute is not often weather dependent, the Sirrus comes complete with front and rear mudguard mounts, so attaching mudguards (available separately) is an easy and quick process. To further aid this bike's versatility, Specialized have included rack mounts, so you can carry all your essentials.
Gearing is accounted for with Shimano's highly versatile 8-speed Altus and Tourney systems. A compact crankset combines with an 11-32T cassette on the back to provide you with smooth and reliable shifting across a range of gradients.
Whether your riding takes you through wet or dry conditions, the linear pull V-brakes will be there to keep your braking sharp and powerful. Keeping you rubber side down, the inclusion of Specialized Nimbus Reflect tyres are a helpful one. These tyres reflect when light is shone upon them, making them ideal for low-light and night riding.
Features
- The reliable and sturdy Specialized A1 Premium Aluminium frame features rack and mudguard mounts, allowing you to carry gear or to fend off road spray in inclement weather.
- A steel, straight blade fork provides a responsive ride, while the fender and rack mounts give you the option to install rain-fighting mudguards and racks that can transport your gear around town.
- V-brakes are dependable and easy to maintain, so you won't have to worry about brake bleeds or labour-intensive maintenance to have awesome stopping power.
