IT’S SIMPLE, THE BETTER YOUR BIKE FEELS, THE LONGER YOU’LL RIDE. HAMMER UP CLIMBS, FLY DOWN DESCENTS ALL DAY LONG.
A versatile design with a longer wheelbase and slightly taller headtube for endurance positioning produces a lightweight, smooth riding feel that makes the road disappear beneath you. Crafted from Giant’s Composite material, the all-new Defy Composite features innovative technologies including the PowerCore bottom bracket and OverDrive headtube for stiff pedaling efficiency and razor-sharp handling. The frame is also RideSense-ready, for use with Giant’s wireless ANT+ data device.

Weight |
How much does this bike weigh? It’s a common question, and rightly so. But the truth is, there are no industry standards for claiming bike weights—and this leads to a lot of misinformation. Variances exist based on size, frame material, finish and hardware. And as bikes get lighter, these differences become more critical. At Giant, we believe the only way to truly know the weight of any particular bike is to find out for yourself at your local retailer. |
