A silly question(5 posts)

I'm in the process of building a road bike using Campy Nuovo Record components (circa 1971). I have several frames I could use-I have a rear wheel that had an 8 speed cassette. Now, for the silly question- will the Campr rear der work in a friction mode with an 8 speed cassette? TIA, I'm sorry if this is a dumb question, but from my handle, you can see I don't have much experience with this shifting thing.

I doubt it. A narrow 6-speed would probably be it's limit. Just go with 120 spacing and a 5 speed, if you're coming off a fixie that's already too many gears for you!
Well, this answer is completely wrongKerry Irons

Campy NR was introduced in 1972, and was "old 6 speed" capable. This means 125 mm spacing, and even then you had some travel left at both ends of the spectrum. Whether it would work for 8 speed friction mode is doubtful but possible. You may just have to experiment.
You should be able to make it work.OldEdScott

I've done similar, although with Suntour Cyclone instead of Campy NR. Just let out the limit screws. I believe you can get enough travel. Cyclone did it without blinking.

Well, I still go with friction shifting. The nice wide spacing of 6 speed cogs makes it easy. 7 speeds get a little touchy, hard to center the chain on the cogs. 8 speeds would be even touchier. It would seem you'd never know when you're in the gear. You'd have a hard time feeling the shift. The Nuovo Record derailleur pulley cage doesn't have enough clearance to shift the chain onto a cog larger than 24 tooth, and the in-out travel might not be enough to cover the 8 cog spread.

Try it. If worse came to worst, you could always use a different derailleur.
