The Specialized Sirrus X 2.0 Step Thru is all about making everyday riding more enjoyable. Whether you’re riding for fitness, running errands, or taking a spin through the park, it offers a smart balance of comfort, control and versatility.
Built around a lightweight A1 Premium aluminium frame, the Sirrus X 2.0 is 1.7kg lighter than comparable hybrid models, helping you accelerate and climb with less effort. Its fitness geometry puts you in a more upright position for improved visibility and control, while the step-thru design makes hopping on and off the bike much easier—great for stop-start city riding or shorter riders.
Up front, a Hi-Ten steel fork provides strength and stability and features mounts for low-rider racks or full mudguards. The frame also includes Plug + Play mounting points, so you can quickly add racks or fenders to suit your daily routine.
The drivetrain is handled by microSHIFT’s Acolyte 8-speed system, offering intuitive shifting and a broad 11–42T cassette that tackles flats and hills alike. Paired with powerful Lee Chi hydraulic disc brakes, you’ll get dependable braking in all weather conditions.
The wheels are wrapped in 700x42mm Pathfinder Sport tyres, which roll quickly on tarmac but have enough volume and tread to give grip on gravel and mixed surfaces. These tyres use Specialized’s Gripton rubber compound to offer confident traction and a smoother ride feel.
Finished with a Bridge Sport saddle and ergonomic touchpoints, the Sirrus X 2.0 Step Thru ensures all-day riding comfort, whatever your journey.
