When the world’s biggest bicycle manufacturer launches a complete range of carbon fibre, disc-equipped road bikes it’s time to sit up and take note – disc brakes are here. Giant have completely overhauled the Defy ‘endurance’ bike for 2015 but while there’s an undoubted emphasis on comfort – down to the carbon fibre layup, tube profiles and relaxed geometry – it’s no slouch. In fact, the flagship Defy Advanced SL frame is the lightest Giant have ever produced at a claimed 890g and the second-stiffest.
The Giant Defy Advanced SL 0 is the top-of-the-range model and comes with a Shimano Dura-Ace Di2 groupset, paired with Shimano‘s R785 hydraulic disc brakes, and Zipp 202 Firecrest Disc wheels. However, if your budget doesn’t stretch to £7,999, Giant’s commitment to disc brakes extends to eight bikes, based on three frames made from varying grades of carbon fibre, and starting at £1,199, while for traditionalists there are also two aluminium-framed machines with rim brakes at the base of the collection.
