Another day, another wheel build (and so on).
Today I built a wheel using a Capleo hub.
There was a problem before assembly.
The Capleo hub is designed for 135mm over-locknut dimension.
The small-wheeled bike I'm putting it on has 130mm dropouts,
so I need to cut 5mm off the axle.
I was thinking maybe that's why there are three 5mm spacers included,
but that turned out not to be the case.
They were three 3.8mm spacers instead.
With 0.5mm spacers on hand
and a spacer or two that's a bit thicker,
I managed to
get it down to 130mm.
However, the spoke angle on the freewheel side becomes nearly vertical,
so this hub will be disadvantageous in terms of left-right spoke tension balance.
I went with a 4-cross lacing pattern.
I could have done 8-cross as well, but with an 18-inch rim being so small,
I was concerned that with 8 spokes, the phenomenon shown by the spokes
painted red in the image above would occur—where
"the inpoke emergence overlaps the outpoke head."
Looking at the actual 6-spoke pattern, it seems like that might have been
unnecessary worry.
It's done. This is the matching wheel for the dynamo hub from before.
Because the spokes are short, spoke deflection is almost zero.
It's the same on the non-freewheel side too, so I can't really tell by touch
whether the 4-cross lacing pattern is having any effect compared to 700C wheels.
The nipples tightened up and the left-right spoke tension difference probably
increased, but again, I can't discern that by feel alone.
One more thing about the included quick-release.
For a proper quick-release that isn't aiming for minimal weight, the axle diameter
is tapered out from the threaded section.
So cutting through the threads and then trimming it down to use on 130mm dropouts
is not a good idea.
The thread's width accommodates everything from narrow steel frame dropouts
to thicker aluminum frame dropouts; it's not designed such that you can
cut it to 130mm and have it work fine.
