Another wheel day (etc.).
A customer dropped off a front wheel laced with an XR200 rim.
It's the companion to the rear wheel I built yesterday with a Hope hub.
DT350 front hub, 20H, four-cross Italian lacing
The spokes are Starbright from Star (they're magnetic, but not as much as the old ones).
Number 15 plain gauge, but they're tensioned so tight that even I wouldn't do it this way.
In that respect and with almost no lateral runout, it's impressive,
but the center offset was only about a sheet of paper—though the radial runout was rather large.
I thought adjustment alone might be enough,
but the customer wanted it rebuilt with CX-RAY,
so a rebuild it is.
Though upon closer inspection, it really did need rebuilding.
The brass nipples with 3.4mm flats were turned with a tool that has short vertical span, so the nipples are partially stripped.
If these were aluminum nipples, they'd break—you can't get this much tension with them.
A tool with short vertical span for 3.4mm nipples... that would be the spoke wrench for Sugino's tension disk, I think.
Even to cut the spokes and disassemble them, you have to release some tension first,
and I struggled just loosening them for that.
Also, the spoke threads are slightly visible coming out from the nipple.
This is clearly a case of spokes that are too short.
All laced up.
CX-RAY four-cross Italian lacing
Aluminum nipples, and the spoke length is flush with the face of the nipple.
Naturally, I've trued the radial runout too,
and the wheel in the image above is spinning.
There's a white band of wear marks on the rim's brake zone,
and when you spin the wheel, this white band dances up and down.
What used to be the case is that this white wear mark was the true circle,
and the rim's outline bounced up and down.
