While sitting under a brideg, waiting out a severe thunderstorm on this morning's ride, I had a
conversation with some fellow cyclists about (what else) other rides we have been on. When I
mentioned a couple I know that have hit 60MPH on a down hill while riding their tandem this one
fellow piped up with "Their wheels aren't rated for that kind of speed!" Say what?!?! I have never
heard of a speed rating for a wheel. He proceeded to inform that at all wheels have a maximum speed
rating and it's based on a rating for the hub and the rim that it's laced to and it's all dependent
on the rider's weight and the maximum speed that the can 'safely' obtain. Again I say, Say what?!?!
He then started quoting all these formulas for calculating the load on a wheel based on all these
different factor and while it didn't make a lot of sense to me I am used to feeling that way when
talk gets technical. When he then quoted an "article from two months ago in Bicycling Magazine" I
was pretty confident that he was spreading a load of (in the words of Peter C) "bugle oil" but I
thought I get some opinions from the learned members of wreck.tech.
What say you?
