. Wish all companies and manufacturers treat their customers like them.But the main issue is to prevent this from happening to someone else, that's why I did send the broken stem, and the new case photos too, so they can study them and decide if a warning or recall is needed, or if it was just an isolated incident.

Indeed. More likely said mechanic overtorqued it. It could also have been damaged in a fall. Regardless, aluminum needs to be inspected for cracks once in a while and discarded at any sign of fatigue.

Actually he was right. As you can see in my latest posts, the problem was due to corrosion caused by sweat and hydration.

Nice! Glad they were so responsive. That's great! Definitely take them up on that.
Looks like improper prep before they painted and not sticking to the metal well at that area
and/or the paint was too thick and the top cap "crushing" the paint, causing it to chip off.
But that's just raw conjecture. Who knows the reality. Profile is just guessing too, until they see the part in detail.
Even if yours failed in this manner, it's not necessarily logical to say others will too.
So, do what you think is right but glad you were not hurt and Profile covered you so well on replacements!

I have a thomson masterpiece seatpost with large holes eaten into it from galvanic corrosion. It was installed in a carbon frame with minimal grease or carbon paste.
I only run carbon seatposts in my carbon bikes after this.
