My road bike currently is set up with Shimano 9 speed stuff, 53/39 front, 12-27 rear, and downtube index shifters. I have been using downtube shifting for years, friction before they had index. (yes I am that old, he,he)(61) Anyway, I am thinking about trying brake shifters either the Shimano Ultegra 9 speed double or the Dura Ace. Pretty good sales going on now for the Ultegra especially.
I hate to ask this but does the Dura Ace last longer than the Ultegra ? Shift any better ? I have been probably making a mistake and reading threads about
brake shifters having problems and being sent back to Shimano for warranty
repairs in less than a year. That is another consideration, the Dura Ace has a three year warranty and the Ultegra has two. One guy says they are more sensitive to worn chains and cassettes and if you change those once a year and flush/clean out the shifters with lube regularly, no problemo. I am curious how they are working for you and which shifters you are using. I did a search and
didn't come up with any comparative info.
