This is a repost below from a post I made in "road," I never got any feedback from anyone who has personally used BOTH D-A 8 speed and ultegra 10 speed. I figure I might find a more receptive audience here. The consensus from the few responses I got was that ultegra 10 is "probably" better than D-A 8. Original post:
Maybe a silly question, but I am hoping to get some reasonable feedback on this (I know, it's BF but hope springs eternal).
I am contemplating an upgrade of my current drivetrain (1980's Dura-Ace 6 speed) to one of the following:
A. Dura-Ace 8 speed (why? because it's compatible with most of my drivetrain including the RD)
B. Ultegra 10 speed (why? because its cheaper and I can just get a new RD with the savings).
Anyway, I am wondering how the performance/quality/durability of these 2 drivetrains compare. I know about the so-called "trickle-down" effect, so I suspect that they are comparable. I would especially appreciate hearing from riders who have used BOTH D-A 8 speed and ultegra 10 speed drivetrains.
