Giant Defy Advanced Pro 3 2021

Oct 2021 · Stu Kerton

Ditch the tyres and you have a fast, sweet-handling endurance machine that doesn't panic at speed

Highs
  • Great ride quality from the frameset

  • Decent tyre clearance

  • Geometry gives smooth handling

Lows
  • Tyres feel a little 'wooden'

  • Not the greatest value spec-wise

Lows
  • Saddle is just okay and bigger bikes need a 160mm rotor on the front

Giant Defy Advanced Pro 0 first-ride review: Super smooth, power meter included - CyclingTips

Jul 2018 · James Huang

Giant’s previous-generation Defy range broke new ground in 2014 by being the first complete range of endurance road bikes from a major manufacturer to exclusively offer disc brakes.

Giant's new Defy endurance bike has several clever comfort features but has the spirit of a superlight racer. We went to Italy for a first ride review.
