I’m not sure which derailleur I will use yet but I plan on using the Rivendell friction shifter, it is good for up to 9 gears.
I've used old bar end friction and thumb friction shifters with 7 to 10 speed cassettes. Also old long cage derailleurs seem pretty versatile.
Will the bike be for trail riding? Lots of climbing?
Also, I have modern XT shifter on my 11 speed mtb and it shifts as well as anything I've ever used. It's as close to perfect as possible, I think.
