Specification

Description

There is no better road machine for long, demanding days in the saddle. Think centuries, sportives and rough roads. The frame is handcrafted with superlight, professional grade Advanced SL composite with endurance geometry for a smoother, faster ride. It features innovative technologies including disc brakes and the D-Fuse integrated seatpost to reduce road vibration. The oversized and tapered OverDrive 2 steerer tube boosts cornering precision. The MegaDrive downtube and PowerCore bottom bracket deliver precise handling and unmatched pedaling efficiency.

The Giant Defy Advanced SL platform is something of a paradox being as it is exceptionally compliant and forgiving yet brutishly strong and powerfully stiff. The Defy Advanced SL is also the lightest frame Giant have ever produced and is one of the stiffest - stiffer than the Propel Advanced SL that has seen Kittel destroying the sprinting field on.

Giant have made significant weight savings by having fewer holes in the frame. Counter-intuitive as that may sound, holes in carbon frames require reinforcement at a penalty of 10g per hole and by utilising existing holes, by routing 2 cables through one drilling and with some tweaks to frame design, the Defy advanced SL is 50g lighter than it's predecessor even with the inclusion of disc mounts both front and rear. Giant have increased the stiffness of the Advanced SL and of the Big Four (Giant, Cannondale, Trek and Specialized) the Defy has the greatest pedaling efficiency giving snappy acceleration, sharp handling and confident ride quality.

Despite the increased stiffness to weight, the Defy Advanced SL is also remarkably compliant making it ideal for the endurance or sportive rider and racer. Giant have achieved this compliance not from the use of gimmicks (no frame inserts for example) but from a Pure Engineering perspective. The rear seat stays are flattened and just 1.3mm thin (any thinner and they would cease to be a tube) and this allows for a precise amount of flex under vertical loads and their junction with the seat tube is lower which creates a leaf-spring effect over their length for smooth riding on rough, uneven surfaces. At the front end the redesigned fork has been slimmed down and is now a more curved shape for balanced ride feel and tuned compliance. Like the bulk of Giant's Avail and Defy ranges, the Advanced SL series features a new carbon D-Fuse seatpost - so called as its profile is shaped like a D and diffuses unwanted vibration to create a more comfortable ride.

All of the carbon Defy models feature disc brakes and these have been seamlessly integrated into the design of the frame. From what we have seen, the Giant Defy Advanced SL 0 is one of the tidiest and maintains extremely clean lines. The Shimano R785 hydraulic disc brakes found on the Defy Advanced SL 0 offer trouble free braking in unpredictable conditions and are never troubled by rough surfaces giving the rider greater confidence and control. A shimano 22 speed Electronic Dura Ace Di2 group is an upgrade over the mechanical of last season.
