I switched to a 1X drivetrain so here is my 2X drivetrain from a 2024 felt breed 820. 48–31 tooth chain ring .  34–11 cassette . Got about 1000 miles on it from the spring still works fine.  It’s got the derailers, the cassette, the front chain ring and two chains. I would get new cables.  This is as is, There are scratches on everything from normal use, but everything works good. you have to know what you’re doing putting these things together. I will ship it for free, but please know what you’re getting into. 
The Shimano GRX 820 2x12 Gravel Groupset is ideal for bicycles used in rough and unpredictable terrains, providing excellent gear shifting and reliable performance while the used condition ensures affordability.
