10s Ergos - working fine last time I used them (2015) but may benefit from a bit of oil on the working parts. I was told when I bought these that the internals had been replaced with Record - no idea if that's true or not but they definitely feel nice. Fair condition, a few scrapes.
9s rear derailleur - I always ran this with the above, I think they're compatible. In pretty used condition, so consider this a freebie.
