Specialized Sirrus 3.0 Disc Hybrid Bike 2022
The Specialized Sirrus 3.0 Disc Hybrid Bike comprises a lightweight aluminium frame and a carbon fork to ensure a lively and enthusiastic ride when tackling frantic commutes and weekend fitness drives. A carbon fork partners the lightweight aluminium frame to deliver a responsive feel, while the balanced geometry affords a comfortable and controlled riding position.
Luggage rack and mudguard mounting points on the frameset mean that longer rides and bad weather are catered for, and strong wheels and grippy tyres grant reliability and grip on poor road surfaces. 2x9-speed gears give a vast range of ratios for tackling any topography, and hydraulic disc brakes promote confidence-inspiring stopping power in all conditions.
