I called Buchanans back, armed with new quesitons. The woman (well she sounded pretty young, but don't they all to us old farts?) I spoke with was pretty easy to get along with today. She claims, despite my skepicism, that there is no difference in the strength of the different rims and that it is NOT easier to pull a nipple through an alloy rim than it is a steel one. She says the different styles are only to offer riders a look and that unfortunatly there is not any way to make the process easier by using science or math!
