Quoted message said:* Are the ripples aligned with the spokes or
independent? *
They are aligned with the spokes, which is really
interesting.
Quoted message said:* Given the extreme tension of the spokes in your ultimate
wheel the rim may be deforming in an unusual way. *
I don't think so, after careful inspection and thought. I
think the wear pattern is a normal distribution of stress
through the rim due to the alternating lateral tension from
the spokes. This rim is super beefy. It could take more
tension than I could possibly put on it and remain sane. In
comparison, the Monty rim bulges noticeably at the spoke
holes until they eventually crack. You would expect
_unusual_ deformation to show up there first because that
is where the most force is exerted on the least area. On my
own wheel, which thanks to Ryan and Ben has seen more
stress than any other Coker wheel (correct me if I'm wrong,
Nathan!), there is absolutely no deformation in that area.
However, both my wheel and Nathan's were from the previous
batch of Airfoils, which had a less-well-conditioned
braking surface; I will be interested to see how the newer
ones wear.
Quoted message said:* If it really was catching and releasing you would notice
a squeal or chatter as you braked. Does this occur? *
Only sometimes if I don't have it toed in a little. I came
to the conclusion that the zero-degree toe-in was for
bikes, not unis.
