Dones anyone know the real difference between Rigida Rims single or double walls
Other than the doubles have 2 walls? Is it stronger? Im a clyde (315#) and choosing between the Knoa Dew and Dew Plus. Wondering if I need to take the wheels into account.

In general, double wall construction is stronger than single.

Double wall is much stronger. For highest durability, get as wide a rim as possible since that would be more laterally rigid. Will go out of true less.

Yes, wheel strength is a big issue at your weight. Wheels designed for loaded touring would be the best situation for you (at least 36 spokes per wheel, touring rims, mountain bike hubs, etc.)-

Thanks for all the help guys, answered my question.

Also larger tyres at lower pressures will lower peak-loads on your wheels. Spreads out the forces over time and distance.

Quite the contrary. It was discussed in the road forums about a year ago (and probably before then as well), and running too narrow of a tire actually makes it compress too much. Your weight will require about the same surface area per air pressure, but a wide and short contact patch (wide tire) will require less deformation of the tire shape than that of a narrow and long patch (narrow tire). Aside from that, getting pinch flats because the tire can't handle absorb impact will slow you down much more.

Double walls on deep rims are the strongest. They look aerodynamic, but the real benifit is in their stiffness. Double depth can give 8 times the stiffness. Keeping the spokes at full tension and evenly tensioned also promotes long wheel life. For someone at 300# spending $50-$60 on a spoke tensiometer is a good investment, even if you dont try to build wheels,

At some point I will. I've learned enough about bikes to know with the right tools I can keep mine running just fine, so long as I watch what Im doing.
