I received a Bora wheel from a customer.
This is the next model after the original Bora (→here),
a Bora with an aluminum brake zone.
The original Bora's rim is definitely Colima (コリマ) made,
but the second generation Bora doesn't look like Colima based on the carbon weave pattern.
However, looking at how the urethane is installed inside the rim, it's probably Colima made.
The customer requested a hub overhaul, truing, and center alignment check.
With hubs from this era, if you put on both left and right dust caps,
you can't tell which side is which anymore.
To be precise, there's the text orientation on the ring that serves as the cover for the grease hole...
The center was off, so I corrected it.
When this Bora came out, there was no Shimano-compatible freehub,
but it was later updated with a Shimano-compatible freehub.
If you were to do this now with currently available parts,
you can only get the newer three-cut notch style freehub body,
so you'd have to swap to a corresponding three-cut notch butted shaft.
However,
this one had an unbutted shaft with a round-hole freehub body.
↑The bearing cone adjustment nut from this era
had a wrench-gripping surface,
but tightening it with a tool often results in overtightening,
so current models have changed to a shape that intentionally can't be gripped with a tool
(only hand-turned) instead.
I performed a hub overhaul,
and since the grease had deteriorated and become stiff, I cleaned and regreased it.
