Product Details

Giant Defy Advanced SL 1 2017

SL means this is the very pinnacle of the Giant Defy Advanced range built on a genuine pro-quality Giant frame. See more.

  • The composite frame is fabricated with Toray's pro grade T800 filament.
  • Although this is Giant's lightest Defy Advanced frame, its Carbon Nanotube Technology (CNT) polymer reinforcement makes it their strongest.
  • The integrated seatpost brings a new level of comfort to the frame while saving more weight.
  • Pro-spec, full Advanced Grade Composite fork with OverDrive 2 (inch and a quarter-to-inch and a half) steerer.
  • Shimano Ultegra-quality 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.
  • 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 over 1,000 euros a pair, Giant's all new carbon composite SLR 1 Disc Centre-Lock Wheelsystem weighs in at just 1,650g (per full wheelsystem).
  • With an up to the minute 23mm wide and 30mm deep rim profile, SLR 1 wheels feature Giant alloy centrelock disc hubs and are clincher and tubeless compatible.
  • 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 fitted with Giant Gavia SLR Tubeless 700x25mm folding tyres.
  • RideSense ANT+ cadence and speed transmitter - compatible with Ant+ cycle computers and home trainers.

Centuries, sportives and rough roads - there is no better road machine for long, demanding days in the saddle. The frame is handcrafted with Giant's superlight, professional-grade Advanced SL composite with endurance geometry. Innovative features including flat-mount disc brake integration, 12mm front and rear thru-axles and the vibration-damping D-Fuse integrated seatpost deliver control and compliance. The oversized and tapered OverDrive 2 steerer tube boosts cornering precision. The MegaDrive downtube and PowerCore bottom bracket produce sharp handling and best-in-class pedalling efficiency.
