I have an 89 Nishiki Custom Sport that I am converting to SS. It has 27 1 1/4 wheels...the rear wheel has a casette. I was planning on using a chain whip and busting the cogs apart, then using the desired cog from the set...

Is that possible? If so do I just need to use spacers to get a straight chain line? Also do you have to have a SS chain or can you use a multi-gear chain?

Thanks for the help
