Well that's basically BS unless they showed you cracks or
kinks from crashing.
Quoted message said:What the heck does he mean "They won't stay true anymore".
I have only had a single pair of rims that wouldn't stay
true, and these were heat-treated rims. Once they bent,
they NEVER got true again, because they were just too
darned stiff.
No matter how much you heat treat aluminum or work harden
it, it's elasticity does not change. I suspect the
wheelbuilder who made the assessment you express had no idea
of how to true a wobbly wheel, or for that matter, what to
do if a rim gets a non-fatal wow in it. This has nothing to
do with heat treatment.
Quoted message said:Assuming your rims are normal raw aluminum or anodized
aluminum, it should always be possible to pull them true.
If not, you can always cut off all the spokes and jump on
the rim till it's flat (don't laugh, i've done this
before.)
Ooooh! That hurts. I see you don't understand wheel truing.
THAT is not the way it is done to any reasonable effect and
it's a huge waste of good spokes. Where do you get these
notions. It sounds so macho however.
Quoted message said:I'm thinking that maybe you need either
Quoted message said:1. new spoke prep, plus re-true
2. new set of nipples + spoke prep, plus re-true.
Quoted message said:Since option #2 is probably about $3 more expensive than
option #1, i'd go with option #2.
Both suggestions should go into the trash bin.
