Jul 2018 · James Huang

Giant Defy Advanced Pro 3 review

Nov 2016 · Robin Wilmott

Smooth, fast, classy and comfortable, the Advanced Pro 3 will go long and stop short. Buy if you want a deceptively fast all-day mile-eater that’s ready to go

Highs
  • Great frameset, handling, fine brakes

Lows
  • Grippy tyres wear quite fast
