Drivetrain switched to 1x with new cassette and chain and front chainring by previous owner. I purchased this locally from the first owner in November of 2023, with 400 miles on it. I rode a total of 900 miles on it in 2024.

It was recently fully professionally serviced by my local bike mechanic (I can provide a receipt for this service). He estimates the chain has another 400-500 miles on it, it's in good condition and has been freshly waxed.

I do still have all the stock 2x chainring, cassette, front derailleur, and cabling, and it would be easy enough to convert back to 2x drivetra...
