An unparalleled combination of comfort, efficiency, and agile handling – the Sirrus X excels on asphalt, gravel, and everything in between. SMOOTH, COMFORTABLE, AND EFFICIENT: The Sirrus X provides the smoothest ride in its class. With larger, confidence-inspiring tires, a slightly more upright seating position, and a super intuitive single-speed drivetrain. RIDER-FIRST ENGINEERED: As with all Performance bikes from Specialized, the geometry of each frame is customized. This means that for every frame size, the tube diameters are specifically selected to achieve the optimal balance of stiffness, weight, and responsiveness – allowing you to enjoy the best riding experience in the world, regardless of your size. AGILE: Class-leading lightweight design, exceptional pedal efficiency, and precise steering ensure safe, almost instinctive handling. - Even lighter than the Sirrus X 2.0 and faster thanks to the added A1 aluminum fork. - Broadly spaced Shimano Cues 1x11 drivetrain with an 11-50T cassette for excellent range on any surface. - More powerful hydraulic brakes for better braking strength and longevity under demanding conditions. - Racktime luggage carrier for your favorite bags and panniers, along with integrated DRYTECH fenders to keep spray at bay. - Especially bright front and rear lights powered by a Shimano hub dynamo – ensuring you can see well and be seen.
