The new Specialized Sirrus X 4.0 is your ticket to riding more, and to places you never imagined possible.
It’s a comfortable, capable, “let’s do stuff” kind of bike that will inspire you to ride more than you ever have before. With bigger, confidence-inspiring tires, a slightly more upright riding position, a super intuitive one-by drivetrain, and plenty of mounts for racks and fenders - it’s more than just a solid partner on the pavement.
The Sirrus X is a dialled option when it’s time to hit some gravel. Specialized has equipped the Sirrus X 4.0 with next-level comfort from their scientifically tested and ergonomically engineered Shared Platform Body Geometry saddle, handgrips, and pedals.
They also equipped Sirrus X 4.0 with the revolutionary Future Shock to take the sting out of bumps and potholes. Here’s to your life on two wheels.
Sirrus X 4.0 Highlights
- Future Shock 1.5 delivers 20mm of compliance to give maximum comfort and control over the rough stuff.
- Added Carbon Fork and an A1 SL alloy frame delivers a build 1.6lb (.8kg) lighter than the 3.0 model–no heavy hybrid featuring a mountain style suspension fork comes close.
- Wide range 1x11 Shimano Deore shifting delivers precise shifting for the long haul.

Unlike many of our competitors, we only make available to purchase online bikes we actually have in stock here in our store − we don't ever remote warehouse or SIM feedstock with multiple day delays.
Furthermore, we aim to have all our bikes pre-built and available for immediate dispatch or for in-store collection, once you have ordered a bike from us one of our mechanics will package your bike into one of our custom-built boxes.
These extra-large boxes allow us to ship most bikes fully assembled but before we do so our mechanics will carry out a PDI (pre-delivery inspection) on the bike to ensure that before it's prepared for shipping everything is set up correctly, e.g., brakes, gear indexing etc.
We ship our bikes pre-built and fully PDI'd so upon receiving your new bike you will simply need to just take your new bike out of the box, turn and tighten the handlebars and fit one of the pedals (if your bike comes with pedals). In some instances, such as for road bikes, you may also need to attach the handlebars as they're too wide to simply be rotated so they'll be secured to the side of the frame with zip ties.
This process does vary from model to model as bikes come in all shapes and sizes but this is the case for nine out of ten bikes we deliver - if you ever have any questions about this please don't hesitate to contact us.
