Specialized Sirrus X 4.0 2021 Hybrid Bike

About the Specialized Sirrus x 4.0

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.

Key Features

• 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.
