7700 rear mech

[KeepItSteel]

Can a 7700 Dura Ace rear mech be used in a 10sp drive train?

Im guessing yes, same freehub width, right?

Slightly narrower chain on jockey wheels should be ok?

no problem whatsoever, prettier than the newer variants as well
In fact I used an 8 speed DA RD with a 105 10sp cassette & SRAM chain without any problem.
