I was wondering, if you were to own a bike with "lower end" Shimano parts and wanted to upgrade to "higher end" Shimano parts, how easily done is this? Can you change one part at a time or do more parts need changing? For instance, if you wanted to upgrade the shifters, would you have to upgrade the derailleur etc also?
Also, if you had a 9 speed cassette, is it possible to change to a 10 speed? From reading around using Google, people say that there are various spacers which can be removed/added if this was the case, but I wondered how true this was.
Thanks.
