I looked up the bike and on bikepedia.com
I only saw a 93, 94 & 98.
The 98 was an IG hub.

The 93 & 94 had a not normal 20-30-42 tooth chain rings with an 11-19 cassette.

Does your bike have those relatively tiny chain rings?
IF it does, make sure you have clearance against the chain stay if going to larger rings.
Depending on how the chain stays bend immediately behind the BB shell, that "might" be an issue.
