There are a few reasons for the early release, but first let me point out that the prices someone above said they experienced seemed high. We have the CAAD9 7 @ $850.00, and the CAAD9 6 @ $999.00. These are msrp, and great pricing considering it's a CAAD9, and comparing it to other bikes with a similar build for '09. You'll note that the CAAD9's have gone down in price for '09 and are still the same quality and made in the US. I think they'll have a hard time keeping up with demand as I believe, though admittedly biased, that these are the best entry-level bikes on the market for 2009.
I believe the reason for the price decrease, and for the early release of some '09 models is two-fold. One, Cannondale always does an early release right around the end of June. Two, Cannondale needed to hit a certain sales number in order for the price for the company that Dorel is to pay stayed high, and the best way to do that was with some stellar deals.
