Subject: RE: Shimano 105 to Ultegra I just ugraded parts of my 105 to partial Dura ace and Ultegra (Dura derailier, Ultegra cassette ). The big reason I upgraded was to go from 8 to 9 speed. If you are already at 9, I think the payoff is minimal in terms of weight shavings. Unless you have already geeked out the other parts that IMO have more payoff (aero/weight wise ) I would spend my $ on trick wheels or aero bars, etc. I am very happy with my mix of parts. The duraace cassettes have titanimum larger rings and the Ultegra was the same as or lighter than my old 8. :- ) |
