If I later decide to put a 10 speed cassette on (to get to my ideal 1x10), would I need to replace the derailleur as well as the shifter? I don't know if derailleurs are "speed" specific.
I didn't realize there were spacers for this purpose - man, I love this forum!
Make sure that what you have now is indeed a cassette, the limited information you provide about your bike isn't enough to know this, most bikes built in the last 10 years with 7 speed shifters use freewheels, not cassettes, not wanting to assume anything I don't know if you will need to buy a cassette
