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.

The Specialized Sirrus X 4.0 is a game-changer. Adding a carbon fork to the X 3.0 model delivers a lighter but still balanced and responsive ride. Combined with an added Future Shock stem and not only more, but longer-lasting, and wider gearing, you'll be comfortable while being unstoppable. 
Lighter and Faster

The carbon fork allows the Sirrus X 4.0 to be 1.6lb (.8kg) lighter than the X 3.0, making it even faster and more comfortable. Whether you’re heading to work or out onto some trails, this lightweight design ensures a smoother, quicker ride.

Wide-Range Drivetrain for Any Terrain

The 1x11 Shimano CUES 11–50t gearing offers you maximum range and simplicity. Transition from climbing hills to cruising flat roads in just a few clicks, the setup is designed for any adventure.

Adventure-Ready Versatility

Equipped with wide 38c Pathfinder tubeless-ready tires, the Sirrus X 4.0 is built to tackle varied terrain with confidence. Tektro hydraulic brakes ensure powerful stopping in any conditions. Add in the Future Shock 1.5 suspension system and rack/fender compatibility, and you've got a bike that's ready for both daily commutes and weekend explorations.
