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!
