Thru Axle Annoyance: Orbea/Tailfin/Ortlieb

[Boopop]

Riddle me this. Why would the top two thru axles thread in (front, rear Tailfin) to my 2021 Orbea Orca, yet the bottom one won't? It's an Ortlieb thru axle for their quick rack. They're all M12x1.0, supposedly. It just doesn't bite in to the thread, wheel in or out.

On the bright side, in the face of minor adversity and frustration, I haven't damaged my frame trying to jam in the Ortlieb axle (as in, I didn't try to jam it in).

Have you cleaned out the threads in the bike frames? Maybe there is dirt in the other two which allows it to bite?

The thread on the end of the Ortlieb item looks a little shiny, suggesting something's not happy.

Have you inspected it to ensure that the leading thread isn't damaged, and tried a vernier over the OD to check it's not oversize?
