Looking for a cheap shifter and derailleur. I have cassettes for 11, 10, 9, and even 8 speed. I want something for my kid hauler and I don't want to spend a lot, so it doesn't need to be nice. Just has to work well. Gotta be less than $80 as I can get a new SLX shifter and derailleur for that and use my old 11s cassette and chain. Bonus points if you have a front shifter and/or derailleur too.
