Specialized Sirrus X 5.0 - 2021

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 5.0 with tubeless-ready tires that nearly eliminate flats and add more comfort and control by allowing for lower tire pressures, and added the revolutionary Future Shock to take the sting out of bumps and potholes. Here’s to your life on two wheels.

- Fact 9 Carbon frame and fork brings race-proven performance and is a full 2.2lb (1kg) lighter than Sirrus X 4.0.
- Full tubeless ready Axis wheels with fast-rolling 38c Pathfinder tires plus Future Shock 1.5 for extreme float, lighter weight, and added comfort.
- Wide Range 1x12 Shimano SLX shifting delivers lightweight, high-performance gearing.
