Specialized Sirrus X 3.0 2026

The Sirrus X provides the perfect combination of comfort, efficiency and agility, excelling both on tarmac and off-road.

Comfort and efficiency
With wide tyres, a semi-upright riding position and intuitive drivetrain, the Sirrus X is extremely comfortable.

Rider-First Engineered
Like all Specialised high-end bikes, the geometry of each frame size has been individually designed to achieve the right balance of stiffness, weight and responsiveness. No matter what the rider's height, the riding experience will be the same.

Nimble
The lightness, efficiency and precision of the Sirrus X give it almost telepathic handling.
