Specialized Sirrus Expert Carbon X1 Disc Hybrid Bike 2017
Where other fitness and commuting bikes tend to err on the side of caution when it comes to striking the balance between performance and comfort and in the end not satisfying either, the Specialized Sirrus Expert Carbon X1 Disc Hybrid Bike 2017 excels at providing both.
The premium FACT 9r carbon fibre satisfies both the comfort and performance aspect of this bike, providing a lightweight, durable and comfortable frameset with Specialized's fitness geometry. This combines with Zertz vibration-dampening inserts in the seat stays and fork, which help to neutralise road vibration.
While a fantastic frameset is one thing, reliable and smooth gearing is another. Thankfully, Specialized have utilised a SRAM 11-speed one-by drivetrain that provides crisp and reliable shifting over a variety of terrain.
Braking is provided by Shimano's Deore hydraulic disc brakes, which provide strong stopping power in both the wet and the dry 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 mudguards
- Shimano Deore hydraulic disc brakes will have you stopping at a moment's notice in any imaginable condition
