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

  • Lays on plenty of smoothness without compromising speed, great value too

Lows

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.
