  • Good spread of gears

  • Excellent hydraulic brakes

  • Reflective detailing is eye-catching

Lows
  • Flat bar makes filtering through urban traffic trickier

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

Specialized Sirrus Elite review

Sep 2019 · Warren Rossiter

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

Highs
  • Excellent kit choices, finish, plenty of mounts

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