Sirrus X

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: The patent pending Compliance Junction frame design of the Sirrus X provides the smoothest ride in its class. Engineered vertical compliance without sacrificing lateral rigidity translates to more comfort, control, and efficiency on all roads, paved or gravel.

RIDER-FIRST ENGINEERED: Like all Specialized carbon bikes, the geometry of each frame is uniquely crafted. This means that for every frame, each tube size and carbon layup is specifically selected to achieve the optimal balance of rigidity, weight, and responsiveness to ensure that no matter what size you’re riding, you’re going to experience the world’s best ride.

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

• Specialized FACT 9r carbon frame features internal cable routing.
• Using our Rider-First Engineered™ philosophy, the geometry of each frame is uniquely crafted. Each tube size and carbon layup is specifically selected to achieve the optimal balance of rigidity, weight, and responsiveness no matter the frame size.
• The Compliance Junction provides just the right amount of flex and forgiveness across the carbon frame without sacrificing performance and efficiency.
• Future Shock 1.5, Specialized’s unique suspension design, is placed inside the headtube to prevent harsh frequencies caused by bumps in the road from reaching the handlebars.
• Wide 38c Pathfinder tubeless-ready tires are ideal for mastering variable terrain, providing traction and comfort off the beaten path.
• The minimalist yet efficient SRAM NX Eagle 1x drivetrain with wide-range gearing ensures smooth and reliable shifting.
• Tektro hydraulic brakes with large 160mm rotors provide reliable stopping power on- and off-road.
• Sirrus X 5.0 is fender and rack compatible with top tube and fork mounts, and racks can be used with 51c DRYTECH fenders, making Sirrus easy to rack and roll.

Sirrus X is your ticket to riding more, and to places you never imagined possible. It’s a comfortable, capable, “let’s do stuff” kind of bike that will inspire you to ride more than you ever have before. With bigger, confidence inspiring tires, a slightly more upright riding position, a super intuitive one-by drivetrain, and plenty of mounts for racks and fenders—it’s more than just a solid partner on pavement. Sirrus X is a dialed option when it’s time to hit some gravel. We’ve also equipped every Sirrus X with next-level comfort from our scientifically tested and ergonomically engineered Shared Platform Body Geometry saddle, handgrips, and pedals. We equipped Sirrus X 4.0 with the revolutionary Future Shock to take the sting out of bumps and potholes. Here’s to your life on two wheels.

• 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 SRAM NX shifting delivers precise shifting for the long haul.
