Specialized Sirrus X 3.0

Stu KertonMay 2022

Hybrid do-it-all with a bit of edge and attitude, just as happy around town as it is on the byways

Pros
  • Capable on the gravel and road

  • Good spread of gears

  • Excellent hydraulic brakes

  • Reflective detailing is eye-catching

Cons
  • Flat bar makes filtering through urban traffic trickier

The Specialized Sirrus X 4.0 is One Heck of a Hybrid

Mar 2020

Smooth, fast, and utilitarian—this commuter has it all.

Pros
  • Future Shock in the head tube smooths the ride

  • Plenty of go-fast and hill-climbing gearing

  • Part smooth/part knobby, 38mm-wide tires

Cons
  • There are more affordable commuter/fitness options out there

Specialized Sirrus Elite review

Warren RossiterSep 2019

A fuss-free commuter with a commanding ride position and a nicely understated style

Pros
  • Excellent kit choices, finish, plenty of mounts

Cons
  • Gearing is great for around town but isn't fast if you head out
