2017 Giant Defy Advanced SL 1 : Ultegra : Composite / Orange

Season:2017

Brand:Giant

Code:701039

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 pedalling efficiency.

The 2017 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 one of the lightest frames Giant have ever produced and is one of the stiffest - stiffer than the Propel Advanced SL that has seen the likes of 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 pedalling 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 1 is one of the tidiest and maintains extremely clean lines. The Shimano R805 hydraulic disc brakes found on the Defy Advanced SL 1 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 Ultegra group takes care of shifting duties and the lighter action of the shifters will mean you won't be fighting for your shifts after a long day in the saddle.

This season Giant once again provide their own hoops in the form of their 35mm full carbon clincher SLR 1 Disc. Giant's wheels are manufactured in-house from only the highest grades of fibre and in collaboration with their long-term partner DT Swiss. Giant design the wheel system from rim to lacing pattern and DT supply the Hub internals like the Star Ratchet freehub system, and spokes. The wheels aren't just another 'hop on the carbon band-wagon' though. Giant have developed a proprietary lacing they call Dynamic Balance Lacing, whereby there is not only different tension between drive and non-drive spokes but also between the 'Pushing' and 'Pulling' spokes on the Drive side itself. Giant claim that this Dynamic system allows for better transmission of the drive forces for greater balance, power transfer and longevity. All good things we think you'd agree.

The new full carbon Giant wheels are a significant upgrade over last year and with no price increase this season, makes the superbly refined and technical Defy Advanced SL 1 better value than ever.

  • 2017 Giant Defy Advanced SL 1 : Ultegra : Composite / Orange review by Neil P, on 10/09/2018

    So much more comfortable for longer trips than my Tarmac, it’s obviously important to get a bike fit as you have the integrated seat post cut to fit. Climbs, descends and stops really well.
