The Specialized Sirrus X 4.0 Disc Hybrid Bike is your ticket to riding more, and to places you never imagined possible. The Specialized Sirrus X 4.0 Disc Hybrid Bike is 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 — the Specialized Sirrus X 4.0 Disc Hybrid Bike is more than just a solid partner on pavement. The Specialized Sirrus X 4.0 Disc Hybrid Bike is a dialed option when it’s time to hit some gravel. Specialized has 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 1×11 SRAM NX shifting delivers precise shifting for the long haul.
