as a Sun rider: what are "mixed results" ?
Is a plastically deformed rim-a state the owner/builder deals with-
more responsive to retrue with an alloy more ductile more malleable
more plastic than a harder alloy?
I undertand what Chalo is writing: metals' characteristics bring each
rim into being but are not defined without tests at limits beyond the
metals intended use.
Yet in designing an ideal wheel-to sell, continue selling, and profit
from-there is an ideal alloy.
maybe, maybe not or somewhere inbetween.
last Sun rims bought for my 29er Monodog are from Universal Cycles,
nicely packed and round round. I was relieved taht's fersure as yes MO
rims are not always.
