Despite being on some really old single-wall wheels, and hauling way more weight than I should be, I've ordered up a pair of double-wall wheels.

Since I set up my current wheels over 1500 km ago, they have never been out of true, and the rim brake surface is still in excellent shape. They have been more reliable than single-wall wheels are supposed to be, from what I hear.

My question is: will I notice any difference while riding after the upgrade?

Context: These are going on my 26" wheel 90s MTB that I use for everything from grocery hauls to very long (150km) rides over mostly paved ways, but also gravel and some offroad (nothing crazy, because I fear injury. LOL).

I'm upgrading more for peace of mind, but an improvement to performance is also welcome.
