A customer brought in a wheel for overhaul work.
It's a ZIPP 404 wheel with a DT front hub and PowerTap rear hub.
I did everything I could — wheel truing, center alignment checks, hub cleaning and regreasing,
tire re-tensioning, and so on.
As for the front hub, since it has ceramic bearings,
there wasn't much to do.
With the rear PowerTap, I always notice
that the tape holding (actually, it doesn't) the magnet
seems to be applied pretty haphazardly.
The magnet is embedded like this.
The tape is just supplementary.
I wrapped it securely with plastic tape.
Unlike vinyl tape, it won't shift from heat exposure.
I thought the rotation felt unusually smooth, and it turned out the rear has ceramic bearings too!
Though I did do a little "good deed" while I was at it.
I cleaned the inside of the hub too.
↑Before cleaning (JIS lacing)
↑After cleaning (Italian lacing)
It seems the lacing pattern changes when you clean the hub.
Yeah right! (← comedy heckling)
The spoke tension on the non-freewheel side was a bit loose, which bothered me...
But that wasn't the original builder's intended tension;
it was just due to spoke stretching or nipple loosening from years of use.
Since the rear wheel was 20H, four-cross lacing wasn't possible,
so I had to make do with four-by-four lacing and build up tension as best I could.
During that process, I had to disassemble the non-freewheel side anyway since it made the work easier.
There was grease at the base of the nipple!
And a washer like this!
Hmm, they really thought this through.
