Single speed to geared bike chain conversion
Hello all,
I am going to be putting the gears back on my wifes old Miyata (attempting to at least)
I have been reading the park tool blue book and it looks like there are different sizes for the number of gears? is this correct? Also is this the only thing i will have to worry about when buying a chain size, (are all sizes compatible with all brands, or will i need to find one that is Miyata specific?)
Thank you for your input, all is greatly appreciated.
