Wheels again today (and so on).
A customer left me a PowerTap SL+ hub in 24H to work with.
Right off the bat—heat shrink tubing, no questions asked.
The bearings on the non-freewheel side had some roughness to the rotation,
so I thought they might need replacing, but after cleaning and regreasing
they smoothed out almost completely, so I left them as is.
I forgot to take a photo before cleaning, but they weren't that dirty to begin with.
Built.
Semi-comp, 46-spoke lacing with wiring. Hmm, looks like "that" showed up again...
The front wheel was also requested, so I built that too.
Evolite hub, 20H, CX-RAY spokes, radial lacing.
I can't go into details, but there's a certain phenomenon that occurs
(and occurs noticeably) only when using asymmetrical lacing on hubs with large enough flanges.
With this level, it definitely shows up. With radial lacing (zero-cross), it doesn't happen regardless of flange size, so
to describe the conditions accurately, it's
"large flange, with the largest possible crossing using tangent lacing,"
probably. In other words, what this blog calls near-tangent or true tangential lacing.
The amount of dish doesn't matter. Whether it's on Amcra hubs (small dish) or
double-threaded large-flange track hubs (no dish),
it comes out the same way depending on how you lace it.
What's curious is that from the perspective of the non-freewheel side of Leaf hubs,
the PowerTap G3 hub has a sufficiently large flange,
so I'd expect it to show about half the phenomenon between Leaf and old PowerTap,
but although the G3 is admittedly larger,
it's not a dramatically noticeable difference.
If you just look at flange diameter, the G3 hub is around the midpoint between Leaf and old PowerTap...
If spoke angle were the deciding factor, you'd see it with small flanges and ultra-deep rims too,
but that condition doesn't produce it.
This has nothing to do with wheel quality, so don't worry about it.
