Please help me brainstorm! I'm playing with the idea of converting my 1990s Giordana from an 8 spd to a 10 spd. I live in Nashville, TN and feel limited. I purchased this bike off of craigslist for 300.00. It has Dura Ace STI shifters, hubs, and rear derailleur. The rest is Shimano 600. I'm thinking that I could sell these parts to help me afford a new group. Now, I'm not exactly sure what this upgrade entails. Would this require me to replace everything? I'd also like to keep the new group accurate to the time period.

I'm not sure if it's worth it. I kind of like the fact that it kicks my ass when I'm doing it for a workout, but not so much for just getting from point A to point B.

I'm looking for some people to help me brainstorm. I absolutely love everything else about this bike.

Any opinions would be much appreciated.

Thanks!

Eric
