Then I think the point of the article was that making a stiff carbon rimmed wheel stiffer with spokes can't usually address a problem brought on by too stiff a rim. The force causing the deflection is at the road and hub. If you can isolate the flex there because the rim is not too stiff, then the part of the rim near the brakes doesn't have to move. If the rim is so stiff that it stays straight and just tilts at the hub instead of actually bending, then you get the movement at the brake and rub. I wouldn't think the small increase in "build" stiffness due to turning the spokes around would fix the problem. Besdes, elbows out (heads in) looks just awful. We do have to keep up appearances, after all.

Not to mention many hubs have a nice lip on them - keeping them from being easily laced elbows out.

You can easily overcome a "stiff rim" with spokes. You have to add more. It's simple and works great. It's why my builds have been as popular as they are.


caloso - because you can't add any spokes to your current setup - simply change the spokes and lace 2X over over radial. Small changes that will add a lot to the feel of the system.
