Specialized Sirrus X 3.0 Disc Hybrid Bike
The Specialized Sirrus X 3.0 Disc Hybrid Bike offers plenty of versatility, from weekday commutes and errands to weekend trips on and off-road. The A1 Premium Aluminium frame has a slightly upright riding position for a good view of the road ahead and increased confidence on trails. Mudguard and rack mounts make it a viable option for use about town in all weathers or for long-distance rides and the wide Pathfinder Sport tyres are ideal for taking the sting out off poorly surfaced roads and gravel trails.
The Shimano single-ring 10-speed drivetrain uses a wide-range 11-42 tooth cassette to give enough gears for the hills, and the hydraulic disc brakes from Tektro add confidence-inspiring all-weather stopping power. Specialized’s contact points like the saddle and grips are well respected for their comfort and ergonomics, making riding a more enjoyable proposition.
Highlights
- A1 Premium Aluminium frame with mudguard and rack mounts
