John M said:... Ultegra and Centaur are probably about equivalent in that they are basically functionally the same as the top groups but with a bit heavier materials and lesser finishes. 105 was a notch below the top 4 Campy groups until it was upgraded to 10s. Now it is probably equivalent to Veloce, although Veloce has (in my opinion) nicer finishes with the polished aluminum than the 105. Tiagra and Mirage are a step down.
I priced the new 105 10s and it seems to be on par with Centaur more than Veloce. Could be price gouging for the new product. Wold you take Veloce over the New 105?
Aesthetically speaking I say currently Shimano has some of the but-ugliest stuff around. At least as far as the cranksets goes. The current Dura Ace crank is the ugliest component I've ever seen on a bike, IMHO. I think all of the Campy stuff is just plain beautiful down to Veloce and even their lesser stuff is nice looking.
Functionally speaking I think if would be safe to say that all the race-worthy stuff works and as it should and as you go up the price ladder, they may work more smoothly and last longer. But to an average-joe-cyclist like me, I may be hard press to tell the differance. Is that a safe assumption? Or is there really a huge difference functionally?
As far as feel, my experience is very limited to test rides and the few bikes I've actually owned so it is very limited. For those that have or had all or most of these groupsets, how would you compare the "feel"?
