Question about compatibility
Hello everyone... I have a quick question:
I ride an oler Paramount OS2. I just bought some new(to me) STI levers off os ebay. Anyway, I have a hodgepodge of older parts on my rig. I am just getting back into it... used to race juniors back in the early 90's. Am I going to run into compatibility problems with these new shifters? That is aside from the obvious number of cogs... Thanks!

I have successfully used 8 speed shifters to shift 7 and 9 speed shifters to shift 8. I would assume that 9 would shift 7.
A derailleur limit screw adjustment was all that was reqired for the odd sized wheel. Since you are not changing wheels your shifters should work.

well, in fact I am trying to find some new wheels and I know that I will need a new derailer for sure... I am on a limited budget right now. My paramount is an oldie, but I love the way it rides. I wish I still had my team issued Viner (columbus SLX) fully decked out with campy c-record!!!! Oh well, back to the basics...

8-speed spacing is the same as 7-speed spacing. And 9-speed spacing is narrower.
if you bought a 9-speed shifter, you can use a modern Shimano derailleur (past 199x ; any of them, except early Dura Ace, I think), and attach the gear cable on the other side of the derailleur. If you need a better explanation, I've heard there is an illustrated one on the https://www.shimano-europe.com website.

If your levers and cogs are incompatible, you may be able to find a cogset with appropriate spacing. Otherwise, there is always downtube or barcon friction shifting, which I still prefer over any indexed system I have tried.
