Specialized Sirrus X 1.0 Step Through

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

With wide-section tyres, a semi-erect riding position, and an intuitive drivetrain, the Sirrus X is extremely comfortable. Like all high-end Specialized bikes, the geometry of each frame size has been individually designed to achieve just the right amount of stiffness, weight, and responsiveness. No matter what the rider's height, the experience in the saddle will be the same. The lightness, efficiency and precise handling of the Sirrus X provide almost telepathic handling.
