Another day of wheel building (and so on).
A customer dropped off a rear hub, and I built a 26-inch MTB rear wheel.
The rim is an Araya TM-840-F silver rim.
I followed Araya's official catalog notation for the hyphen.
It's a 26-inch HE rim, but pretty much all manufacturers have discontinued theirs,
making them extremely difficult to obtain.
The point of this wheel was "replacing a rim that had exploded spoke holes,"
but the customer wanted a silver rim even if it wasn't the exact same model,
so I had to search pretty hard. I don't actually know what the original rim was.
Single-wall rims like those on mama-chari (utility bikes) do exist,
but they're not really an option. When it comes to double-wall rims, they're genuinely unavailable.
ALEXRIMS makes a silver rim for the DM-18,
but the distributor had no stock,
so I went directly to another distributor looking for Araya rims.
They had some of the black TM-840-F rims,
but the silver one wasn't there.
However, later they called to say they'd found just one,
and that's the rim we ended up using this time.
FH-M760 XT hub, 32H
Campagnolo/Comp 4-cross lacing, no J-bend.
Backing up chronologically,
when the hub arrived, it already had lateral play.
As spoke tension was applied, the play got worse,
so after a preliminary wheel build I adjusted the ball seat,
but once I tightened it past a certain point, the hub axle suddenly locked up solid.
It wouldn't turn.
Ah, I see what's happening...
Sure enough, the right-side bearing dust cap was installed backwards.
The customer had apparently greased it before bringing it to our shop,
and made a mistake during reassembly.
Got the orientation sorted out.
