Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Specialized Sirrus X 4.0 Hybrid Bike - Gloss Smoke/Cool Grey

Season:2021

Brand:Specialized

Code:301101323217

The Sirrus X is a comfortable, capable bike that will ignite your passion for cycling like never before. Boasting larger, confidence-inspiring tyres, a slightly more upright riding position, and an intuitive one-by drivetrain, it's not just a reliable partner on pavement, it's your go-to choice for gravel adventures. Equipped with ample mounts for racks and mudguards, the Sirrus X is ready to tackle any terrain with ease. Plus, every Sirrus X is outfitted with next-level comfort from scientifically tested and ergonomically engineered Shared Platform Body Geometry saddle, handgrips, and pedals. The Sirrus X 4.0 takes comfort to the next level with the revolutionary Future Shock, providing maximum comfort and control over rough surfaces. Here's to embracing life on two wheels with confidence and style.

Featuring Future Shock 1.5, the Sirrus X delivers 20mm of compliance to smooth out bumps and potholes, ensuring a comfortable ride on any terrain. With an added Carbon Fork and A1 SL alloy frame, the Sirrus X 4.0 is built 1.6lb (.8kg) lighter than the 3.0 model, setting a new standard for lightweight performance in the hybrid bike category. Its wide-range 1x11 Shimano Deore shifting system delivers precise gear changes for long-distance rides, while the Pathfinder Sport 700x38 front tyre offers reliable traction and durability on varied surfaces.
