I am looking at the possibility of upgrading to Dura Ace 7900 shifters (long story) but have not found any super positive reviews. And in terms of using them for cross, really have not found anything positive or negative. My only real concern I guess is the openness of the internals on the underside of the shifters and the chances of dirt and mud getting in there.
So who is currently running them and what do you think? Worthy upgrade?
