It doesn't have the rough ride normally associated with an aluminum bike.

Sprinting is another whole story though. It's very stiff and compliant. There's no give when you stand up and pedal on the CAAD10. It just goes.

As far as upgrading from a CAAD9 to a CAAD10, it's probably not worth it. But if you're in the market for a new bike anyways, the CAAD10 is a better choice.
