Specialized Sirrus X 4.0 Fitness bike | Gloss Smoke
Fitness
The perfect bike to tackle your fitness goals is the one that checks all the boxes and gets you off the couch and moving. Fast and smooth? Check. Comfy ride position? Check. Body-Geometry-Tested touchpoints with a performance mindset? Triple-check. If health is wealth, we say these fitness bikes are exactly what the doctor ordered.
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.
LET’S RIDE
With Sirrus X, confidence lives hand-in-hand with comfort, without compromising the ride itself. To put it another way—it’s a comfortable, capable, “let’s do stuff” kind of bike.
Our game-changing Future Shock brings cutting edge suspension technology to your ride. Future Shock helps reduce impacts from a rough ride by nearly 40% when compared to bikes with heavy front suspension forks. Who needs the dead weight?
Sitting on top of the A1 aluminum or optional Fact 9 carbon frame you’ll be in the perfect position to comfortably reach the bars and pedal efficiently. Working hand in hand with Future Shock, wider tires absorb road bumps, provide confidence in the dirt, and deliver greater stability at all speeds. Add our scientifically tested Body Geometry saddle, grips, and pedals to this recipe and your hands and butt will stay comfy on rides of any length.
No user manual needed. Simple 1x shifting means you have one intuitive place to change gears but with all of the capability of a more complicated, high-maintenance setup. Hydraulic disc brakes come standard on all models for more stopping power in all conditions and less frequent maintenance.
