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.

SKU: N/A Categories: , , , ,

 

  • 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.
