Welded rims may also use locating sleeves in manufacturing. I have had a few (can’t recall the brand/model) that clicked under load. I could see the sleeve through the valve holes. Used a latex craft glue to secure them. This was pre-tubeless.
Lennard, maybe I missed it but what brand of TPU tube have you had good luck with? I had an experience similar to yours with a glued-in presta stem (my hand pump took the stem off with it) and another unexplained leakage of a spare … I’m 0 for 2 using TPU tubes as spares.
I am not sure I have yet had good luck with any thermoplastic urethane (TPU) tube. I have only used Tubolito and Eclipse TPU tubes. The former had the glued-in valve core issue we were discussing, and the latter’s sudden failure triggered this post.
