Replaced the Front Wheel Rim on My Single-Speed Bike

Relocated the rim the other day

The match to the rear wheel.

Large flange hub 32H with nut-threaded axle.
Laced in JIS-pattern, plain 14-gauge.
While I'd like to switch to Italian lacing for the rim replacement,
that would require flipping the inpoke and outpoke on one side of the hub flange,
or treating the rim as reverse-drilled if it had no hole offset.
Too much hassle, so I'm just relocating the rim instead.
Which means the wheel stays laced in JIS pattern after the swap.

I forgot to shoot this when I did the rear wheel,
but here's the spoke head stamping on Richey spokes.

Got it laced up. The rim is an ALEXRIMS R450, same as the rear wheel.
I specify ALEXRIMS because DT had a rim with the same name a while back,
but that one never came in silver,
and besides, you don't usually mix them up anyway.

Had 2 spokes that needed replacing (coincidentally, the rear wheel also needed 2),
so I'm patching them with DT Champions.

The rim side wear was much worse than on the rear rim,
with the wear indicator groove actually protruding,
tightly closed and sharpened to a point.

↑Originally had this shape,

ground down to a curve and thinned out,

and deformed like this, apparently.
A rare case where what was once a depression has turned into a protrusion.
The brake shoes had also worn down to a sharp groove in the center,
so I swapped those out while replacing the rim.
