The Giant Defy Advanced Pro 1 is an endurance road bike built for riders who want to cover serious distance without giving up performance. The Advanced-Grade Composite frame pairs with an Advanced SL-Grade Composite fork featuring a full-composite OverDrive Aero steerer — stiff where you push, compliant where you feel the road.
The fully wireless SRAM Rival eTap AXS drivetrain removes cables from the equation entirely: no housings to replace, no barrel adjusters to fiddle with. The 12-speed 10-36 cassette gives you a wide enough range to handle climbs and long flats alike. The Giant Power Halo power meter, built directly into the crankset, lets you manage your effort with precision — a feature more commonly found on higher-priced builds.
The Giant SLR 1 36 Carbon Disc hookless carbon wheels (36mm depth, 22.4mm internal width) come fitted with Giant Gavia Fondo 1 tubeless ready 32mm tyres, sealant included. Running tubeless cuts puncture risk, allows lower tyre pressures and noticeably smooths out rough surfaces. Frame clearance extends to 40mm for even more versatility.
The D-Fuse SL composite handlebar and seatpost round out the vibration-damping package, filtering out road noise exactly where your hands and hips feel it most. Available in Meteor Storm colourway, sizes S through XL.
