Any pics? I agree witht he others nothing wrong with bikes, now french people..... OH back to the bike, any pics?
I would check the demensions of the spindle and see what cranks you can run on it. You should be able to find a crank that will fit the bill. 165 seem real shoer you must be quite the spinner. What gearing was on your Bottecchia?
Depending on where you live a 28/38/48 triple may be a bit too compact but paired with something like a 6spd 13-25 should give plenty of low gear and adiquate high unless you want to race, or do fast club rides.
This VO crank would look great on a vintage Frenchie.

It comes in 165 and paired with there threadless BB isn't something you have to leave behind if you move on from Stella.
