Another day of wheel building (details omitted).
Built the rear wheel for Nomu-Lab Wheel #5 using a DT240 hub.
28H, black semi-comp lacing pattern (4-cross),
with gold aluminum nipples.
I'll do the spoke tie-in later.
Going back in time a bit—the star ratchet freehub was making an abnormal grinding noise when coasting.
I wondered if I had the bamboo-shoot spring oriented wrong or if the ratchet teeth weren't meshing properly,
but when I took it apart, I discovered
the culprit: there were two bamboo-shoot springs
installed on the freehub body side.
DT hubs as distributed through Japanese wholesalers only come
in Shimano HG or SRAM XDR freehub body configurations,
and Campagnolo freebodies have to be purchased separately
and swapped in after the fact.
So this one was presumably swapped in (from Shimano),
but it looks like an extra spring got installed in the process.
The hub body side had one bamboo-shoot spring, oriented correctly.
I reduced the freehub-side spring to just one and reassembled,
and the coasting feel became normal and smooth again.
Also, the star ratchet grease seemed a bit sparse,
so I've reapplied it.
