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.

  • 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 shifting delivers precise shifting.
This bike is built with a Specialized A1SL Premium Aluminum frame featuring Fitness Geometry, butted tubing, internal cable routing, flat-mount disc compatibility, a quick-release system, and Plug + Play mounts for racks and fenders. Up front, it’s equipped with a Specialized FACT 9r Carbon Monocoque fork with Future Shock 1.5, flat-mount disc, 12x100mm thru-axle, low-rider mounts, and Plug + Play fender mounts, providing a smooth and controlled ride. Stopping power comes from Shimano BR-MT200 hydraulic disc brakes with 160mm rotors both front and rear. The drivetrain is driven by Shimano Cues components, including SL-U6000 11-speed shifters, an 11-speed Shadow Plus rear derailleur, a CS-LG400-11 cassette with a wide 11-50T range, and a Prowheel alloy crankset sized appropriately per frame with a Narrow Wide 42T steel chainring, paired with a threaded BSA bottom bracket and KMC eGlide chain designed for Cues. Rolling on durable 700C double-wall alloy rims with 22mm depth and 21mm internal width, the wheels use stainless 14g spokes, sealed cartridge hubs with Center Lock disc mounts, and thru-axles (12x100mm front, 12x142mm rear), matched to Pathfinder Wirebead Fast Gravel 700x40C tires and standard 40mm valve tubes. The cockpit includes alloy mini-rise handlebars with 9-degree backsweep and 15mm rise, a Future Stem Comp, Specialized Neutralizer Body Geometry locking grips, a Body Geometry Power Sport saddle with steel rails, and an alloy 2-bolt seatpost with 14mm offset secured by a 31.8mm bolt-type binder. Rounding it out are Specialized platform pedals, making this a well-rounded build for fitness, commuting, or gravel adventures.
