The 2025 Specialized Sirrus X 4.0 Hybrid Bike takes elements from gravel and mountain bikes to make the Sirrus X your ticket to riding more, and to places you never imagined possible.

The Sirrus X is the replacement for the Specialized Crosstrail which was one of their best-selling bikes for years. The Sirrus X does away with the old style suspension fork that came on the Crosstrail to save a whopping 1.7kg, making the bike lighter, faster and easier to carry if you need to get it up and down stairs. With bigger, confidence inspiring tyres, a slightly more upright riding position, a super intuitive one-by drivetrain, and plenty of mounts for racks and mudguards the Sirrus X can handle more than just your daily commute. Sirrus X is also a dialled option when it's time to hit some gravel at the weekends. Every Sirrus X comes with next-level comfort from scientifically tested and ergonomically engineered Shared Platform Body Geometry saddle, handgrips, and pedals.

The Sirrus X 4.0 comes with Specialized’s own Future Shock 1.5. Normally found on their endurance road bikes the Future shock allows 20mm of movement in the fork to soak up bumps without adding the weight of a traditional suspension fork. 1x 11 Speed Shimano gearing make this bike capable of tackling any hills you want to point it at.

This bike is perfect for

Anyone who wants a bike that can handle the daily commute and take you exploring on gravel roads, dirt tracks and cycle paths at the weekend. The super simple design makes this bike easy to maintain and easy to live with. With the addition of the Future Shock and 11 speed gears this bike is really capable off-road.

Key Features

  • Future Shock 1.5 delivers 20mm of compliance to give maximum comfort and control over the rough stuff.
