Specialized Sirrus Sizing

Specialized suggests sizes but we'd always recommend test-riding the bike as everyone has different proportions and preferences. We'd say it's especially important if you straddle two sizes.

If you feel little difference between sizes, opting for the smaller generally offers more adaptability down the line. Bikes can quite easily be made to feel bigger, but when trying to shrink a bike that feels too big, your options are more limited.

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 pedalling efficiency, and steering precision merge for confident, nearly telepathic handling characteristics.

  • Future Shock 1.5 delivers 20mm of compliance to give maximum comfort and control over the rough stuff.
  • Added Carbon Fork and an A1 SL alloy frame delivers a build 1.6lb (.8kg) lighter than the 3.0 model – no heavy hybrid featuring a mountain style suspension fork comes close.
  • Wide-range 1x11 Shimano Cues gearing delivers precise shifts for the long haul.
