Giant 2025 Defy Advanced Pro 0 PowerMeter Road Bike

Description

Expect More From Your Bike

With effortless efficiency and quiet compliance, the lightweight 2025 Giant Defy Advanced Pro 0 is a buttery smooth endurance road bike that helps you do more of what you love. And equipped with Giant's Power Pro Powermeter, you'll be ready for serious data-based training right out the box.

An all-new Advanced-grade composite chassis combines responsive efficiency with a calm, composed ride quality. The combination of a D-Fuse seatpost and handlebar, both featuring D-shaped tubing to better absorb shocks and vibrations, helps you stay smooth no matter how rough the road. The new Contact SL AeroLight stem has cleanly integrated cable routing. And the frame has clearance for high-volume tires up to 38mm.

A double winner, the Defy Advanced Pro was crowned Bike Radar's 2024 Endurance and Overall Bike of the Year, with editors proclaiming: "This light and fast bike is a class leader and outstrips rivals costing much more. If you're seeking your next endurance road bike, I can't think of a better place to start (and finish) looking."

Giant Power Pro

This fully integrated, dual-sided power meter measures power output and delivers accurate data to help you track, analyze and improve your performance on the bike. Engineered with multi-axis left and right crank arm sensors, the Power Pro displays vital information including power (watts), pedal balance, force angle and cadence. The meter pairs with ANT+ head units and its battery lasts up to 150 hours (or 1500 miles) of riding on a single charge and is easy to re-charge.

Functional simplicity

Free of cumbersome gimmickry, the frameset is one of the lightest in its category. With a perfect balance of high-performance reactivity and all-day comfort, it offers a "less is more" experience. Advanced-grade composite frame and fork are specifically engineered for endurance road riding, delivering a smooth and efficient ride quality that minimizes fatigue on long rides. The new D-Fuse components work together to further absorb road shocks and vibrations.
