I have a 1996 Trek 7900 carbon/aluminum frame (all '96s were green/gray carbon) that I'd like to restore back to original specs. BikePedia lists mostly Shimano Deore LX components, but not which model numbers. So far I've found out the rear derailleur is a Deore XT SGS M739, but that's it. If you have one of these and could help out with some specifics or close-up photos, I'd greatly appreciate it.
