Looking for something for trainer duty, so range doesn’t really matter much. Used is fine as long as it has some life left on it.
Umm, if it’s just for trainer duty, you could probably get Deore or Tiagra brand new from Amazon for around $30. Just sayin’
I have a few in a box at home. Looking for a specific range?
Honestly most anything would work 11-25 or 11-28 would probably be ideal given the chain/RD.
i have a 105 12-27, 105 11-28 and a 105 12-25. All good enough shape, stopped using when I upgraded to 11sp a few years ago. I can take pics on one and send to you. say, $25 shipped lower 48.
PM sent!
