It's believed that this will be the last US made CAAD9. The CAAD series used to be at the top of Cannondale's lineup, now that everyone's gone carbon-crazy it's a very light frame at an affordable price.

The most important thing is what feels better to you though. Ride them both, ride some other bikes, and see which one you like best.
