I purchased a full set of the AXS stuff to upgrade to electronic, but opted to stay with my XX1 gold crank/chain/cassette, so selling the parts I took off (shifter, derailleur) and the new AXS stuff I didn't use. Here I'm posting my mechanical Eagle XX1 shifter and rear derailleur. They came on my bike when I purchased in early 2018 and I have put about 500 miles on them according to Strava. I'm more of an xc rider, and in fact the bike is a hard tail, so that should tell you something. Great condition, with the usual scratch here and there.

Asking $200 for the derailleur, $125 for the shifter. Or maybe $300 for both? Also selling the new AXS stuff, so you could combine these with the rainbow AXS chain/cassette and DUB crankset to have a really sweet 12 speed upgrade with mostly new parts.
