Offering an unprecedented combination of comfort, efficiency, and nimble handling, the Sirrus X excels on pavement, dirt, and any terrain in between.
SMOOTH, COMFORTABLE, AND EFFICIENT: Sirrus X provides the smoothest ride in its class. With bigger, confidence-inspiring tires, a slightly more upright riding position, and a super intuitive one-by drivetrain.
RIDER-FIRST ENGINEERED: Like all Specialized performance bikes, the geometry of each frame is uniquely crafted. This means that for every frame, each tube size is specifically selected to achieve the optimal balance of rigidity, weight, and responsiveness to ensure that no matter what size you’re riding, you will experience the world’s best ride.
NIMBLE: Class-leading light-weight, exceptional pedaling efficiency, and steering precision merge for confident, nearly telepathic handling characteristics.
- Even lighter than Sirrus X 2.0, and faster thanks to an added A1 alloy fork.
- Wide-range 1x11 Shimano Cues drivetrain with a 11-50t cassette gives excellent range on any road.
- More powerful hydraulic brakes for enhanced braking power and durability in tough conditions.
- Racktime rack for your favorite bags and panniers, and integrated DRYTECH fenders to keep the spray away.
- Extra-bright front and rear lighting powered by a Shimano Dynamo hub to see and be seen.Cockpit
