Giant Defy Advanced Pro 1 2019 - Endurance Road Bike

This Giant DefyAdvanced Pro 1 is one of the best looking Shimano Ultegra disc brake carbon road bikes featuring carbon wheels with tubeless tyres for a smoother ride and fewer flats. Find out more about what's new in the Giant Defy 2019 range, read our Giant Defy Advanced Pro 1 review or take this bike for a demo and try it for yourself.

Spec Highlights

  • Pro-spec, full Advanced Grade Composite fork with OverDrive 2 (inch and a quarter-to-inch and a half) steerer
  • Shimano Ultegra flat mount hydraulic disc brakes are smoother, better modulated and more powerful than even the best cable-operated disc brakes. Why you should consider a bike with high quality hydraulic disc brakes
  • Shimano's latest Ultegra 8000 STI 2x11 shifters, gear mechs, cranks and cassette are even closer to Dura-Ace level in terms of their smooth, slick and precise performance - whisper it but they'll have you questioning the need to spend more on Di2
  • The Shimano Ultegra Hollowtech crankset saves weight
  • Another upgrade UItegra riders particularly appreciate is that it offers a firmer shift than 105, delivering a quicker downshift onto the smaller ring under pressure
  • Giant SLR 1 Disc WheelSystem - designed as a system, not as a collection of separate components - for performance, strength and enhanced acceleration potential. The benefits of system built wheels
  • Retailing on their own at around £1,000 a pair with tubeless tyres, Giant's carbon composite SLR 1 Disc Centre-Lock Wheelsystem weighs in at just 1,650g (per full wheelsystem).
  • Up to the minute 23mm wide and 30mm deep rim profile, SLR 1 wheels feature Giant alloy centrelock disc hubs
  • SLR 1 wheels are built using Giant's Dynamic Balanced Lacing system - so spoke tensions balance out as riding forces are applied, resulting in a stiffer, more efficient wheel
  • 12mm front and rear thru-axles beef up the wheel-to-fork and wheel-to-frame interface and help eliminate judder
  • For an even smoother ride and extra puncture resistance, the wheels are set up with Giant Gavia SL Tubeless 700x28mm folding tyres
  • The benefits of tubeless tyres
  • RideSense ANT+ cadence and speed transmitter - compatible with Ant+ cycle computers and home trainers

Giant Defy Advanced Carbon Composite Frameset

  • Every Defy Advanced Pro frameset is fabricated in-house by Giant, from its raw performance-grade Toray T-700 carbon filament to its final lacquered finish, 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

How do they do it? More Engineered-in Benefits

  • Making it disc brake-specific means the frame doesn’t require a rear brake bridge
  • Having no brake bridge to support allows Giant to spec skinnier seatstays
  • Giant Defy Advanced seatstays are as skinny as you will get – any thinner, the stays would be rods, not tubes
  • Fewer holes – for instance, both 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, which adds extra weight
  • Being disc-specific the wheel rims are thinner walled to reduces rotating weight

Giant D-Fuse SL 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.
