Specialized Sirrus X 4.0 EQ

The Sirrus X 4.0 EQ: Your All-Terrain Adventure Partner

The Sirrus X 4.0 EQ 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 this in mind, you’ll find it’s more than just a solid partner on pavement. The Sirrus X EQ is a dialed option when it’s time to hit some gravel. Furthermore, it includes bigger, confidence-inspiring tires, a slightly more upright riding position, and a super intuitive one-by drivetrain.

The Sirrus X 4.0 EQ: Next-Level Comfort

We’ve equipped every Sirrus X with next-level comfort from our scientifically tested and ergonomically engineered Body Geometry saddle, handgrips, and pedals. In addition, we equipped the Sirrus X 4.0 EQ with the revolutionary Future Shock to take the sting out of bumps and potholes. The Future Shock 1.5 delivers 20mm of compliance to give you maximum comfort and control over the rough stuff. Consequently, the added Carbon Fork and an A1 SL alloy frame deliver a build 1.6lb (.8kg) lighter than the 3.0 model—no heavy hybrid featuring a mountain style suspension fork comes close.

Sirrus X EQ: Integrated Features

The wide-range 1×12 Shimano Deore shifting delivers precise shifting for the long haul. Moreover, you can add a Racktime rack for your favorite bags and panniers, and integrated DRYTECH fenders to keep the spray away. We also include an extra-bright front and rear lighting system powered by a Shimano Dynamo hub so you can see and be seen. Ultimately, this bike is a celebration of your life on two wheels.
