But what really sets this road bike apart from the competition is its built-in compliance and endurance geometry, which absorbs road shocks and vibrations to give you a smooth ride that's easy on your body. You'll be able to ride longer and push yourself further without feeling the fatigue that comes with rough roads.
And let's talk about control - with disc brake integration and flat mounts, you'll enjoy consistent braking power even in the roughest weather conditions. Plus, the 12mm front and rear thru-axles give you the stability and control you need to take on any road or mountain pass.
But don't think this road bike is just for the smooth pavement - its versatility and endurance road geometry give you the freedom to tackle any terrain or condition. With up to 35mm of tire clearance, you can take on rugged backroads and mountain passes with ease.
So what are you waiting for? Whether you're an experienced rider or just starting out, the Defy Advanced Pro 2 Di2 Road Bike is the perfect companion for your next adventure.
Advanced Composite frame is engineered for endurance road riding. The D-Fuse seatpost and handlebar absorb road shocks and vibrations, and its smooth ride quality means you’ll feel less fatigue on long rides.
Disc brake integration, including flat mounts and 12mm front and rear thru-axles, produces more consistent braking power for better control, even on rough roads and in all kinds of weather conditions.
Endurance road geometry, plenty of tire clearance (up to 35mm), and disc-brake integration allow you to tackle a variety of roads and conditions, from smooth pavement to rugged backroads and mountain passes.

Weight
The most accurate way to determine any bike’s weight is to have your local Bicycle Warehouse weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.
