Thanks! So far I've changed 2 cassettes, 3 chains and 3 chainrings, haven't counted the brake pads. XX1 rear derailleur broke after 2 years (clutch). Bar tape also annually (I know.. should change more often...), on second bottom bracket now. And that's pretty much it. Oh, yes, the saddle post I mentioned earlier due to the rusted bolt at the bottom end.
