2007 Trek 1500 "downgraded" 1600 10speed added.

Hey i found these links surfing google. 1500 are all 105, no ultegra rears anymore, still 9speed. And the 1600 has the same mix 105 front & ultegra rear as the 06 1500s did but the 1600 is a 10-speed.

Just passing this along for anyone considering waiting for the new models or trying to jump on a discount for 06 models.

I have been told that the new 105 10 speed derailleur is supposed to be better than the old Ultegra 9 speed derailleur. The Specialized Roubaix Elite is switching from 9 speed Ultegra on the 2006 model to 10 speed 105 on the 2007 model.
