Giant Defy 3

Top-level road performance, right within your reach. It's light, it's efficient and it's smooth as silk.

Built with many of the same design philosophies as bikes ridden by Giant pros, TCR Composite delivers sharp handling and snappy acceleration with just enough compliance for racing and long training days. The PowerCore bottom bracket area and asymmetrical chainstays produce maximum pedalling efficiency. The OverDrive steerer tube technology, which features a tapered, oversized design, adds front-end stiffness and steering precision. The frame is RideSense ready, for use with Giant’s ANT+ wireless data transmitter.

OTHER
Weight The most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All Giant bikes are designed for best-in-class weight and ride quality.
