Maybe the P1 bikes follow a different scheme? I wouldn't bet money on any of this being correct - all I know is that the Trek rep told me this morning that the first part after WTU is the production date, the middle part is the factory code, the last part is the bike's position on the day's production run, and that the 'R' at the end marks my Domane as a 2021.
