2027 Specialized Sirrus X 2.0

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.

Class-leading light-weight, exceptional pedalling efficiency, and steering precision merge for confident, nearly telepathic handling characteristics.

• Lightweight A1 Alloy frame with clean internal cable routing, 3.5lbs (1.7kg) lighter than the Crosstrail Hydro model.
• Maximum control through intuitive shifting with 1x9, 11-46t wide range gearing, and powerful hydraulic disc brakes.
• Float over rough terrain with fast rolling Specialized Pathfinder 40c tires featuring proprietary Gripton rubber compound.
