Another day with wheels (and so on).
A customer brought in a front wheel from a Cannondale Hologram 35
for me to work on.
They wanted it rebuilt.
All the stickers on the rim had been peeled off, leaving it unmarked,
and for a moment I thought maybe
it had been laced onto a different rim with the same rim depth and internal nipple design.
But I have telltale signs that prove this is actually a Hologram rim—
it's simply a rim with the stickers removed.
It's built with round section spokes in a 2:1 lacing pattern, and
it's laced radial, so the tangent-laced side is quite loose.
When you squeeze this tangent-laced side (the final crossing is braided),
it makes a pretty pronounced scratching noise pretty easily.
I initially thought it was because round spokes make point contact rather than the flat contact of aero spokes,
but then I realized
it's actually the excessively glossy
friction resistance between the paint coatings
that seems to be the bigger factor in the noise.
This wheel is made by XERO (Zero), and
while not all parts are completely in-house production,
they do have custom-spec'd components
like spoke nipples and bearing seals with their own logo stamped on them.
I've rebuilt it.
I went with a reverse-asymmetric lacing pattern using black CX Sprint spokes.
I'll do the lacing thread later.
Like the Rovel which is also laced radial,
the CX Sprint on the lower spoke count side is
now much more tensioned than before,
and the left-right difference in spoke deformation is
reduced compared to the original,
but the tangent-laced side with its acute final crossing angle
is still fairly loose.
So as I was planning anyway,
the lacing thread is essential.
