Giant Defy Advanced SL 0 Bike
The Giant Defy Advanced SL 0 is the endurance bike that never asks you to slow down.
This is Giant's flagship endurance road bike, built for riders who go far and refuse to compromise. The Defy Advanced SL 0 uses the lightest, most advanced carbon Giant makes, so a dawn-to-dusk loop from the Valley to the coast feels lighter in every mile. Race speed and all-day comfort, no trade-off.
It's right for you if:
You ride centuries, gran fondos, or all-day epics and want zero excuses.
You already know your numbers and want the best frame money buys.
You want race speed with true endurance comfort underneath you.
You're ready to invest in a bike you'll keep for a decade.
Why you'll love it:
The top-tier carbon frame is feather-light, so long climbs stop feeling long.
The D-Fuse seatpost and bar soak up road buzz, so mile 80 feels like mile 8.
Electronic shifting fires off crisp, instant gear changes every single time.
Carbon wheels spin up fast and hold speed on the flats.
Hydraulic disc brakes mean total control on fast descents.
The tech you get: an Advanced SL top-grade composite frame and fork, electronic Di2 shifting, carbon wheels, and hydraulic disc brakes tuned for endurance riding.

Highlights
Advanced SL Composite Frame
The flagship of the Defy range uses Giant's lightest, highest-grade carbon for endurance riding. Super light and silky smooth, it is built to go long and go fast without wearing you down.
D-Fuse Bar and Seatpost System
The D-Fuse handlebar and seatpost flex together to absorb road shock at both contact points. Rough chip-seal and cracked pavement stop rattling into your hands and back.
SRAM RED eTap AXS Wireless
Top-tier wireless electronic shifting delivers instant, flawless gear changes with nothing to trim or cable to stretch. The lightest, most precise shifting SRAM makes.
CADEX 36 Hookless Carbon Wheels
Wide 22.4mm-inner hookless rims run high-volume tubeless tires up to 38mm at lower pressure. That means more grip, more comfort, and less rolling resistance mile after mile.
Contact D-Fuse Handlebar with 8-Degree Flare
The flared drops give you a more natural, controlled grip on long descents and rough roads. Confidence right where you need it when the hours stack up.
PowerCore Bottom Bracket
An oversized bottom-bracket and chainstay area keeps power transfer tight even on an endurance frame. You still get a snappy, efficient bike when you decide to push.
