An unparalleled combination of comfort, efficiency, and agile handling – the Sirrus X excels on asphalt, gravel, and everything in between. SOFT, COMFORTABLE AND EFFICIENT: The Sirrus X provides the softest ride experience in its class. With larger, confidence-inspiring tires, a slightly more upright seating position, and a super intuitive single-speed drive. RIDER-FIRST ENGINEERED: As with all performance bikes from Specialized, the geometry of each frame is individually tuned. This means that for each frame size, the tube diameters are specifically selected to achieve the optimal balance of stiffness, weight, and responsiveness – so you can enjoy the best riding experience in the world, regardless of your size. AGILE: Class-leading lightweight construction, outstanding pedal efficiency, and precise steering ensure safe, almost intuitive handling. - Even lighter than the Sirrus X 2.0 and faster, thanks to an additional A1 aluminum fork. - Broadly geared Shimano Cues 1x11 drive with an 11-50T cassette, providing excellent range on any surface. - More powerful hydraulic brakes for improved stopping power and durability in challenging conditions. - Racktime luggage carrier for your favorite bags and panniers, along with integrated DRYTECH fenders to keep splashes at bay. - Especially bright front and rear lighting, powered by a Shimano hub dynamo – ensuring good visibility for both you and others on the road.
