Sirrus X is your ticket to riding more, and to places you never imagined possible. It’s a comfortable, capable bike that will inspire you to ride more than you ever have before. With bigger, confidence inspiring tyres, a slightly more upright riding position, a super intuitive one-by drivetrain, and plenty of mounts for racks and fenders/mudguards, it’s more than just a solid partner on pavement.
Sirrus X is a dialed option when it’s time to hit some gravel. Every Sirrus X has been equipped with next-level comfort from Specialized's scientifically tested and ergonomically engineered Shared Platform Body Geometry saddle, handgrips, and pedals. Specialized equipped Sirrus X 5.0 with tubeless-ready tyres that nearly eliminate flats and add more comfort and control by allowing for lower tyre pressures, and added the revolutionary Future Shock to take the sting out of bumps and potholes. Here’s to your life on two wheels.
- Fact 9 Carbon frame and fork brings race-proven performance and is a full 2.2lb (1kg) lighter than Sirrus X 4.0.
- Full tubeless ready Axis wheels with fast-rolling 38c Pathfinder tyres plus Future Shock 1.5 for extreme float, lighter weight, and added comfort.
- Wide Range 1x12 Shimano SLX shifting delivers lightweight, high-performance gearing.
LIGHT AND SMOOTH WITH FUTURE SHOCK
The Future Shock is a revolution is smooth, delivering 20mm of travel without degrading speed, handling, or comfort. It does quite the opposite. Through a focus on axial compliance, it breaks the mould of what was thought possible in bicycle design.
THE SOLUTION - FUTURE SHOCK
The Future Shock features up to 20mm of travel, and it's positioned above the head tube in order to move in a vertical path. So when the front wheel encounters rough terrain, the bike moves up towards your hands and preserves your forward momentum without slowing you down. Another important fact is that, because the Future Shock is positioned above the stem, the bike's wheels are held together rigidly by the frame. In other words, because the wheelbase isn't changing throughout the suspension's travel, like with traditional system, you get the added benefit of extremely predictable handling.
