Giant Defy Advanced 2 2019 -  Endurance Road Bike

Giant Defy Advanced 2 is one of the world's most advanced carbon road bike frames: Shimano 105 drivetrain and tubeless tyres equipped.

Previously reserved for Giant's £2K-plus Pro models, every Giant Defy Advanced model rolls on tubeless tyres for extra comfort and fewer punctures. Why this is a good thing. Also, read more about what's new in the Giant Defy 2019 range

Giant Conduct hydraulic disc brakes
Giant's unique take on cable-operated hydraulic disc brakes: each brake is initially cable controlled from the Shimano 105 STI brake lever, but only to its reservoir, which is hidden under the handlebar stem from where a hydraulic line connects it to the caliper. The benefit of this system is that you get the improved power and modulation of a hydraulic brake while the caliper is much neater than previous hybrid cable/hydraulic systems for road bikes. See Giant video.

Giant Defy Advanced Carbon Composite Frameset

  • Every Defy Advanced frameset is fabricated in-house by Giant, starting with performance-grade Toray T-700 raw carbon fibre to create a stiffer, lighter weight and more compliant ride.
  • Blending Toray T700 carbon filament and resin with vibration-absorbing particles helps maximise rider comfort and frame strength (hence the lifetime guarantee).
  • Modified Monocoque Construction: the front triangle is assembled and moulded as one continuous piece.
  • The main frame is then joined to the rear chainstays and seatstays in a secondary process.
  • This process eliminates the outermost woven composite sheet to reduce weight without affecting ride quality, strength or stiffness.
  • The seatstays are as skinny as you will get - any thinner, the stays would be rods, not tubes.
  • These stays don't just lower the frame's weight, they work with the D-fuse composite seatpost to help create the bike's road-buzz-defying magic-carpet ride.
  • Fewer holes - for instance, both internally-routed derailleur cables are routed through one hole in the head tube not two. That's significant because holes in carbon frames have to be reinforced, so reducing the number of holes saves weight.

Giant D-Fuse Seatpost

The Giant D-shaped carbon composite seatpost works in tandem with the skinny seatstays to do a remarkable job of damping bad vibes that would otherwise be transmitted from unsmooth road surfaces.

Giant Defy Advanced 2 Features

  • The Advanced Grade Composite frame delivers an optimal balance of speed, responsiveness and shock absorbing comfort.
  • Giant's endurance road geometry with slightly longer head tube and longer wheelbase creates a fast exciting bike that doesn’t ignore your comfort needs.
  • Its sportive geometry (72.5 degree head angle / 73 degree seat tube angle and tight rear triangle) means a Giant Defy Advanced never feels flat or dull. It responds like a road bike to your efforts. You pedal: it goes. Yet it's forgiving nature makes a Defy an excellent choice for a 100-mile sportive.
  • The lightweight shock-absorbing Advanced Grade Composite carbon fork legs further contribute to the Giant Defy Advanced's responsive, fast-steering, exciting ride.
  • The fork's Giant OverDrive Steerer tapers from one and an eighth inch external diameter at the top to inch and a quarter at the crown.
  • As well as building their own frames and forks, Giant extrude their own rims to build their own high quality wheels.
  • Because it's a disc brake bike, Giant reduce the wall thickness of their rims to reduce the wheel's rotational weight.
  • Giant then equip their wheels with their own tubeless tyres.
  • Controlling every aspect of designing, engineering and building the wheelset ensures every component works perfectly with its partner to create a more laterally stiff wheel which will take less effort to accelerate faster.
  • On the same principle, the tyre fits the rim as though it was made for it - which it was.
  • The Shimano 105 STI (Shimano Total Integration) gear shifters are integrated with the brake levers so you can change gear any time without having to remove your hands from the brake lever hoods
  • The wide-range gearing (34/50 chainrings and 11-34 cassette) makes a Giant Defy Advanced suitable for the type of challenging varied terrain you would typically encounter at a sportive or similar long-distance ride.
