Why would you ride a conventional road frame when you could get a frame that is lighter, stiffer and more responsive? That was the notion that Giant designers and engineers started out with more than 10 years ago when they revolutionized the cycling world with the introduction of the very first compact road design. A design that changed the way the UCI regulates bicycle design and innovation. A design that has gone on to win numerous Tour stages and championships, and a design that ultimately has become the benchmark for which all other compact road bikes are held in comparison.
By effectively sloping the top tube downward at the seat stays, Giant designers were able to reduce the overall size of the front and rear triangles resulting in Giant's now distinctive compact look. An appeal that has garnered Giant's Compact Road design recognition and acclaim the world over.

Functionally our compact configuration reduces weight; increases lateral rigidity and acceleration speed (power to the ground for sprinting and hill climbs) and provides for just the right amount of compliance to make your ride enjoyable.

Fewer frame sizes make finding the right size frame for you a snap.
