Specialized Sirrus X 1.0 Step Thru 2025 - Hybrid Sports Bike
The Specialized Sirrus X 1.0 Step Thru is a versatile hybrid that’s perfect for anyone who wants a confidence-inspiring ride for commuting, weekend fitness rides or just getting from A to B in comfort. Its lightweight A1 Premium Aluminium frame is not only easy to handle but also 1.7kg lighter than Specialized’s Crosstrail Hydro model, making it a great option for riders after a responsive and manageable bike.
Key Features:
- Lightweight A1 Premium Aluminium frame with upright Fitness Geometry
- Hi-Ten steel fork with low rider rack and mudguard mounts
- Shimano 1x7-speed drivetrain with wide-range 12-40T cassette
- Tektro MD-U310R mechanical disc brakes for reliable stopping
- 700c alloy wheels with 42mm Pathfinder Sport multi-surface tyres
- Step-thru frame design for easy mounting and dismounting
- Available with 0% APR finance
The step-thru frame design makes getting on and off the bike easy, particularly handy in stop-start urban environments or when carrying luggage. The upright riding position enhances visibility and comfort, while internal cable routing gives the frame a clean, modern look.
A Hi-Ten steel fork with rack and mudguard mounts adds everyday practicality, allowing you to fit extras for commuting or touring. Meanwhile, the 1x7 Shimano drivetrain keeps shifting simple, with a wide 12-40T cassette offering the gears you need to tackle varied terrain.
Tektro mechanical disc brakes provide confident stopping in all weather conditions, while 700x42mm Pathfinder Sport tyres give you the versatility to roll smoothly on tarmac and handle light gravel paths with ease, thanks to Specialized’s grippy Gripton compound.
Finished with thoughtful details like a comfortable Bridge Sport saddle, alloy seatpost and quality double-wall wheels, the Sirrus X 1.0 Step Thru offers everyday performance in a relaxed, accessible package.
