thanks, i may be wrong with the year of the bike. im just going on what i was told by others. the headbadge wasnt recognizable and theres no info on a "zebra" 10 speed except references to zebrakenko but non of them are clear.

as far as issues, could you elaborate?

im tinkering with this because i already have a carbon framed bike with a custom build cassette/compact crankset combo and a retro italian with a sti/custom cassette. i wanted to make this heavy bike more climbing friendly, expecially with the panniers full. as long as the thunderbird/eagle derailleurs can work with the triple conversion then it will get me up the hills i need to just to get home. theres a bunch of vintage parts floating around ebay still so i could get nicer condition replacements when i get to the point of restoration.
