Specialized Sirrus Sport review

Oct 2017 · Oli Woodman

A classy, dependable option but one that's neither particularly quick or comfortable. Buy if you want a dependable commuter bike and aren't often in a hurry

Highs
  • Calm, upright position, great gears and brakes, nicely finished

Lows
  • Sluggish tyres, not particularly comfortable, only average in value terms
