Hey there guys!
I would like to convert my old Nishiki ( over twenty-years-old) bicycle, into a more modern-looking 24, 27, or 30 speed bike. I would like to also convert from friction to indexed shifters.
I was told that the clearances between my rear drop-outs were too small to find a modern match, because my bike is too old.
However, I could possibly find reconditioned or slightly new componentry to upgrade my Nishiki.
Could someone explain all of this to me please?
