Giant Defy Advanced SL ISP Road Bike Frame

Description

Professional teams asked for a lightweight, stiff, alternative-geometry bike for longer distances and rougher roads. The all-new Defy Advanced SL is the answer. Built with Advanced SL-grade composite, and system-engineered with the new oversize OverDrive 2 headtube and fork-plus the RideSense ANT+ sensor for wireless data transmission-it takes the endurance road bike beyond integration. A MegaDrive downtube and PowerCore bottom bracket add unmatched stiffness, precision and pedalling efficiency.
