Specialized Sirrus X 2.0 Disc Hybrid Bike
The Specialized Sirrus X 2.0 Disc Hybrid Bike features a lightweight and strong aluminium frame to grant an energised riding experience when darting across town on errands or tackling challenging weekend gravel rides. The frame donates a more upright riding position, and this teams with the strong wheels, grippy, high volume tyres and an ergonomic saddle to guarantee comfort and composure across rougher terrain.
Luggage and mudguard mounts make commuting in the rain more bearable, while a 1x8-speed gear configuration with a wide range of sprockets means that any hill or headwind is conquerable. Hydraulic disc brakes are added to the build and ensure confidence-inspiring and safe stopping power in all weather conditions.
Highlights
- A hardy hybrid bike with a multifaceted performance that’s suited to tarmac and rough gravel
- The aluminium frame is lightweight and efficient, promoting a lively ride character
- A slightly more upright riding position affords extra confidence and control
- Luggage rack and mudguard mounting points facilitate longer trips and combat bad weather
- Strong wheels and high volume tyres handle rutted terrain with aplomb
- A wide-range 1x8-speed gear setup delivers precise shifting
- Hydraulic disc brakes stop powerfully in all conditions
