This lightweight composite road bike is designed to smooth out even the roughest roads, so you can go the distance without feeling like you've been run over by a truck.

But this isn't just any old road bike - it's engineered with endurance geometry and built-in compliance, so you can ride for hours without feeling the burn.

So whether you're a seasoned pro or just starting out, the Defy Advanced Pro 1 Road Bike is everything you need for your most challenging rides.

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.
