Hi guys,
First of all thanks for all replies.

So, the narrower the rim (considering both are made of the same thickness of metal) would be the stronger rim.
Second, let me excuse myself for my bad english (not my mother tongue) - i meant "narrower", not "thinner".
jj1091, i understand your example, as i also understood what the mechanic said.

Knowing beforehand that I am comparing apples with oranges as there are many variables out there, I should then reformulate my original question:
are the apples (MX19) stronger than the oranges (XL25) for a fully loaded offroad touring bicycle?

(Once again, my english and lack of technical skills are not enough for understanding this. My intuition is that what you refer to is that a 11-speed cassette takes wider space than a 7-speed cassette and therefore the wheel will be less "symmetrical" and therefore more imbalanced? I find this marketing stuff of "oh so many gears" totally annoying. I have a 9 gear cassette and only use the even numbers, so it means that a 5 gear cassette would be enough, as far as I have a big granny gear. So, as a side-question, if i want to "downgrade" to 7-gear, do i need a new rear rear hub?)
Regarding the number of spokes, i was wrong. I was convinced that i had 32, but both models i refer use 36.
