    Single wall rims have 1 wall and form a U cross section. Double wall rims have 2 walls forming a box between the tube and spokes. A triple wall has, surprise, 3 walls!

    See the difference in double and triple wall at the link below.

    Strength (ex. rope) and rigidity (ex. glass) are not the same thing. You need a balance between the 2 to get a useful rim.

    Box sections allow more more rigid rim designs all things being equal. Rims with wall thickness that's too thin can be very wobbly despite the number of walls. Balance is important.

    Sun and Weinmann rims are quality rims, but a number of wheel builders I respect prefer Mavic. Mavic is more expensive because of good designs and quality control.

    Single wall rims are cheaper to make and not as strong. A double wall rim forms a box when looking at a cross section. It makes for a very strong structure that resists bending.

    Rims with double walls are stronger and more rigid, so they will last longer and stand up to abuse better.

    I don't see why you will agree with anyone else if the bike shop tells you a perfectly good answer and you disagree. They are the ones that will have to warranty a new bike. If they sell you junk they have to replace it and they have the skin in the game. We don't here. Tell you what. If you are convinced you need something, why don't you buy it? Don't ask, just do it.
