Specialized Sirrus Sport Carbon Disc Hybrid Bike 2017
Introducing the Specialized Sirrus Sport Carbon Disc Hybrid Bike 2017. A lightweight carbon fibre frameset combines with a range of performance, comfort and durability focused components that ensure you are ready to tackle everything from your daily commute to your loftiest fitness goals.
Having fun on a bike has a great deal to do with comfort. That is why Specialized have used their premium FACT 9r carbon fibre to construct this bike's frameset. This combines with Zertz vibration-dampening inserts in the seat stays and fork, which help to neutralise road vibration.
Combined with the top quality of this frameset is the crisp and precise shifting provided by the mix of microSHIFT and Shimano components. The 9-speed drivetrain is ideal for powering along the flat or putting in a big effort on a climb.
Confidence-inspiring braking is provided by Shimano's M315 hydraulic disc brakes while the Body Geometry engineered contact points at the saddle and handlebars are designed to keep you riding comfortably hour after hour, day after day.
Features:
- The FACT 9r carbon fibre frame is engineered and designed with Specialized's Fitness Geometry, helping you ride more efficiently in a position that will see you riding comfortably, mile-after-mile.
- Zertz inserts in the lightweight FACT carbon fibre fork absorb road vibration to make a smoother, more responsive ride, while the Plug + Play mudguard mounts give you the option to install rain-fighting fenders.
- Shimano M315 hydraulic disc brakes will have you stopping at a moment's notice in any imaginable condition.
