best way to upgrade late 80's suntour superbe pro group

I recently picked up a Fuso with mostly suntour superbe pro components. I was wondering how much of the current group set I could keep if I wanted to upgrade to indexed shifting (ultegra perhaps). Is it possible for me to upgrade just the shifters? Would that even work??

Shimano brifters won't work with a Sun Tour freewheel (I assume it is a freewheel) or cassette and the widest freewheels available in Shimano (or Shimano compatible) form are 7-speed. At minimum you will need a new freewheel, chain and shifters (assuming you can find 7-speed ones) and likely a front derailleur if you want to use brifters.

You might do better to sell the Sun Tour parts to a collector or to someone doing a period restoration and start wih all new components. Check out the C&V forum to see what interest there is in these items.

I'll happily ship you a 10 speed cassette and 10 speed brake/shifters in trade for your superbe parts. PM me.

Upgrading an old frame, unless you have sentimental attachment or it is a really gorgeous frame, is rarely worth it, financially.

Well, I think the frame merits an upgrade someday but as of right now, I don't know if its worth the complete upgrade just for indexed shifting...

leave it just as it is. and save up for a modern bike with modern components if that's what you want. vintage road bikes are dead sexy. i've got a complete black 105 9 speed group that i'd trade (with wheels) for the complete group off that bike.

You don't upgrade Suntour Superbe Pro.
