yeah, well, I just bought and used mavic open series rims, never
really noticed the difference in the names- as opposed to selling
them, I just rode them and liked them a lot; certainly for the smooth
braking surface. the point about not re-using old spokes was truing by
hand as opposed to tensionmeter, is that you need the same feel with
all the spokes, when they are used, even with a quick rim swap, I
found the truing process harder and "less true" with grime collected
on the threads for the nipples and finger-tips from spoke plucking-
not to mention the grain and even overall length of a used spoke will
interfere with that feel. Further, I find it difficult to believe that
a used spoke which has it's own unique bend or shape and length
according to it's previous life- will be able to instantly adapt to
the new shape required of a new rim; meaning that I believe the used
spoke will hold much of it's old shape and gradually adapt to the new
shape following which, the wheel will no longer be in balance with all
the forces that held it true- it will require frequent re-truing which
is indicative of a weaker wheel.
