Designed to meet the needs of hard, fast races and long, gruelling rides the Giant Defy Advanced 1 combines an advanced grade composite frame with Giant's endurance geometry to offer the perfect blend of stiffness, weight and road smoothing compliance.
The Giant Defy Advanced 1's frame is packed full of performance features including an OverDrive 2 steerer tube to boost front end stiffness and control to create a razor-sharp handling bike. The PowerCore bottom bracket area turns your power into positive forward motion with minimal reduction making the Giant Defy Advanced 1 one of the most efficient road bikes available.
Equipped to the Giant Defy Advanced 1 Road Bike is a host of premium components from leading brands including a smooth, reliable and race ready 11 speed Ultegra groupset combined with a selection of Giant's premium contact finishing kit to create an affordable, professional grade racing bike.
Giant’s all-new chainstay-integrated, wireless data transmitter. The removable transmitter sends wheel-speed and cadence information directly to any ANT+ compatible computer.
As the first manufacturer to bring the tapered headtube to market - with the 2006 Glory mountain bike - Giant knows a thing or two about inventing solutions for improved steering precision. The original OverDrive technology resulted in groundbreaking stiffness-to-weight ratios, and now Giant is doing it again with an all-new standard: OverDrive 2.
Compact Road Design
In 1997, when riders on the legendary Spanish pro team ONCE rolled up to the start of a race on a compact geometry Giant bike, the competition didn’t quite know what to think. For decades before that moment, the design and geometry of road bikes had remained essentially the same. Giant’s new approach was a radical departure, and we called it Compact Road design.
High-performance T-700 raw carbon fiber is used to produce custom composite material in Giant’s own composite factory. Extremely lightweight, stiff and compliant, these handcrafted frames feature the monocoque construction.
