Would this work in friction-mode as long as the rear derailleur limit screws are adjusted properly?

I don't believe that old friction barcons were speed specific, but they did come on 5 speed bikes, I have a Schwinn Sports Tourer on hooks with the optional Schwinn barcons controlling a Campagnolo Gran Sport and 14-34 5 speed Schwinn approved freewheel, the one with the 1" pitch on the two big cogs.

I'd be willing to bet that the Suntour friction barcons have enough cable pull to shift 8, 9, and maybe even 10 speed. Whether or not you'd WANT to shift that thin spacing with friction is another matter.

I've got two bikes that I run 8 speeds in the rear with barcon shifters (pre-indexing) and they work fine. I had to get the rear tensioned just right before I could make it to the lowest cog with consistency.

Is that 130mm spacing on that 8 speed or 126mm? If 130mm there'd be no reason you couldn't shift 10 speed. If 126mm, and you have to be that careful of the tension, there might not be enough pull for 9-10 speed?

BarCons shift over 8sp without a hitch. 6/8 speed is better than 7/9/10, but they'll do it all.

Which does bring an indexing question into it... With a 6 or 7 speed setup- Shimano indexed shifters, can you make indexing work on, say a Huret derailleur with a Suntour freewheel? Or is this just a case of "try it, it's so crazy- it just might work"?

How about Suntour ratcheting Thumbshifters with a Shimano derailleur and an SRAM cassette? CRAZY world going on out there!!!
