Specialized Sirrus X 1.0 Step-Through in Marine/Grey Blue

Season:2025

Brand:Specialized

Code:42220495382811

The Specialized Sirrus X offers an unprecedented combination of comfort, efficiency, and nimble handling, excelling on pavement, dirt, and any terrain in between.

Sirrus X provides the smoothest ride in its class. It features bigger, confidence-inspiring tyres, 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 are 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.

Features:

  • Lightweight A1 Alloy frame with clean internal cable routing, 1.7kg (3.5lbs).
  • Maximum control through intuitive shifting with 1x7 wide range gearing.
  • Float over rough terrain with fast rolling Specialized Pathfinder 42c tyres featuring proprietary Gripton rubber compound.
