It's simple: the more comfortable you are in the saddle, the better you can perform. Climb, descend, sprint - all day long.
With its longer wheelbase and slightly taller headtube for endurance positioning, Defy Composite gives you a lightweight, smooth riding feel that makes the road disappear. Crafted from Giant’s Composite frame material, it features innovative technologies including the PowerCore bottom bracket and OverDrive headtube for stiff pedalling efficiency and razor-sharp handling. The frame is also RideSense-ready, for use with Giant’s wireless ANT+ data device.
