Can I change my Nishiki 7 speed circa 1986 from a 7 speed to a 9 speed. I have components. A SRAM 9 speed cassette. Can I just by a 9 speed back wheel?
I have end bar shifters that are friction. Is there a limit on what their shifting range is? i.e. will it have the range to shift to all 9 gears?
I have a Tiagra RD to replace the SunTour one.
Thanks. Trying to see if I can use my spare parts for upgrades.
