Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Group set question

I have a CAAD 4 that i bought only to realize it's way to small for me, my next purchase was a TCR With the 105 group, my question is the CAAD 4 has the Ultegra crank, brakes and flight deck levers, and rear derailleur would it be worth it to switch components from the CAAD 4 to the Giant ? Is there a big difference between the two ?

First things first. Does the 105 group on the TCR have the same number of speeds as the Ultegra components on the CAAD4? If not, they are not really compatible with each other. New 105 is probably much better than old Ultegra

Assuming they are the same vintage..and, as @alcjphil points out, they may not be ... functionally you will notice no difference between the two. You will save a small amount of weight making the switch.

Do you notice much difference between the two? If you have the old bike and the new bike, and they are both tuned correctly, then you should be able to judge if one shifts better than the other in the ways that matter to you.

CAAD 4, "flight deck" tells me that's a pretty old ultegra. Probably worth just selling it intact and enjoying 105 on your new bike.
