Dura Ace 7900 Rear Derailleur
Can anyone tell me if the Dura Ace 7900 rear derailleur will work with Ultegra SL shifters off a 2008 Madone.

Yes they are 10 spd shifters, but I've read a lot about the Dura Ace 7900 not being compatible with older shifters. I've found a new derailleur for a price I can't pass up, I just want to make sure that it will even work with what I have. Thanks

According to teh shimano compatibility chart, it is only compatible with ST-7900 - various other internet sources claim that the rear derailleur IS backwards compatible - just not the front.
