Never knew it could be so complicated!
With winter being half the year, I thought there was plenty of time to upgrade my old Paletti Classic road racing bicycle with some newer technology. Now, with spring closing in I have some dilemmas to solve before getting out on the road and the snow is beginning to melt.
I have taken off a damaged crank set and purchased an Ultegra FC6600 hollowtech double crank set 10 speed compatible. Only after did I realize that this will require a narrower chain than my old-style chain servicing a 20-year-old 6 speed freewheel. I really don't want to upgrade to a new wheel set , but I wonder if there is a "thread- on" 6, 7,or 8 speed freewheel with inter-cog spacing that will work with the necessary 10 speed chain (or can I use a 8 or 9 speed chain). From many of the posts I have read on this fantastic forum I have the impression that the narrower chain may risk catching between the cogs. Also, what is the likelihood I may continue to use my old front Campagnolo derailleur? Front and rear shifters are both nice functional friction style. thank you so much for your input. I look forward to hearing from anyone who has solved a similar dilemma!

Hi kpmupnorth, have you got photos of the Paletti?

Too bad. Well, you might try asking this question in the Classic & Vintage forum, or the Bicycle Mechanics forum. I'd go for the C & V forum first, because we will all want to see your bike

Oh, and get better soon!

The narrower chains are intended to fit the narrow spacing on the 9 and 10 speed cassettes. I'm pretty sure you'll be okay with your current chain, as most modern cranksets work with backwards compatibility. If you need a new chain, go for a nice SRAM 8 speed.

chain width
But I'm afraid that the wider chain is going to rub or bind against the larger (outer) chainring when it is seated on the inner (smaller )front chainring. Maybe I'll have to reassemble the gear, installing the new crank. Maybe this won't be a problem. Tanks for the advice all.

Nope. It'll work. You might want to look for an ultra-seven speed freewheel from Suntour, but that probably isn't needed. The 9-10 speed chains need the narrower cogs, but I'm pretty sure that you'll be happy with an 8-speed chain. The black SRAMs are cheap and look appropriate.

If you want verification from an authoritative source, check Sheldon Brown on Harris Cyclery:

7-speed, 8-speed 9-speed, 10-speed?
Component manufacturers like to sell you lots of new parts, even if you don't need them. This has led to much confusion as various parts are labeled as if they are incompatible with other parts even though they are not.
The following parts ONLY are "speed specific":
* Indexed Shifters These need to have the correct number and spacing of detents ("clicks") to match the system they'll be used with.
* Cassettes It is really the cassette that determines how many speeds you have in back.
* Chain As you go to more sprockets on the cassette, you need a narrower chain. However, using a narrower chain with an older system rarely presents any problem.

I am never sure of anything, but I think that Suntour offered a seven-speed freewheel that was the same width as their six-speed conventional stack - thus the "Ultra" designation. And a way to get an extra cog into the same axle and dropout spacing that you currently have, if you are running six. I used to dream of a 12, extra. Now I think that a 26 would be most appropriate.
