|Are D/Ace and Ultegra 8spd stuff compatible ?||PeterRider|

|I thought, after reading many posts on this forum, that D/Ace and Ultegra 8spd stuff were compatible with each other without any problem.
I was going to get on ebay a 8spd D/A 7402 rear derailleur, and put it on my full-Ultegra-double/8spd (about 1997) equipped bike, and the seller tells me that this vintage of DA works only with DA stuff, and that I would have to change the shifters too.
Is that true ?
Actually I would also have the same question about the front D/A derailleur, model 7410 braze-on.

|The Dura-Ace 8/9 speed barend shifters are 8-speed compatible ONLY with a Dura-Ace 8spd rear der, is how I found this out..
per Sheldon 'fount of wisdom' Brown,
Old-style Dura-Ace used a shorter cable throw per shift than other
Shimano stuff, up until the 9-speed version came out in 1997. The
9-speed shifters are compatible with all 9-speed derailers/clusters.
Folks who have old-style Dura-Ace 8-speed stuff are not S.O.L.,
however, because 9-speed shifters (_all_ Shimano 9-speed shifters)
index with 8-speed cassettes _IF_ used with an _old-style_Dura-Ace_

|If your using downtube shifters on your Ultegra bike, all you have to do is change to D/A downtube shifters and you can get those pretty cheap. If your Ultegra is STI, than you are looking at an expensive change just to get an 8 speed D/A rear derailleur. Eight Speed D/A STI's are very expensive. They almost cost as much as the nine speed STI's( which also work with 8 speed)|
