cracked anodizing can and does initiate fatigue. but since all rim
cracks are observed to be a function of the extruded material's
anisotropy, not actual anodizing cracks, the misattribution of anodizing
to be the cause of cracking in bicycle rims simply demonstrates analysis
failure. as one might expect if the analyst was trying to use a[n
inappropriate] dye penetrant test to make the connection.
your post is simply the desire to deflect from the mistake of excess
spoke tension - a mistake that's cost the industry, manufacturers and
bike shops alike, millions.

As yet there's no proof of that, it's only your own unsupported claim.
Jobst's claim is much better supported by the observed evidence.

Am I missing something, or wouldn't this experiment have benefitted
from a unanodized control sample?

... given a liberal definitions of talk. I find rbr a
relief from the petty bickering elsewhere; an island of
calm in an increasingly contentious world.

I think you've trawled this troll-bait enough.
How about becoming again a relevant RBT contributor? It's not hard to come
up with fresh good links, and I'll lead by example.

Excellent link! I'm indebted, purple ano is getting almost impossible to
find anymore, now I can make my own!
