Another day with wheels (and so on).
A customer dropped off a rear wheel that we built for them some time ago.
AL22W rim, Ebolite hub, 28H
Semi-championship pattern lacing with reinforcement.
While we don't brand wheels built with this rim as
Nomulabo wheels,
it's essentially the wide-rim version of the Nomulabo wheel #5.
Rather than 24H, we used 28H, and instead of semi-comp
we used semi-championship lacing,
building it as stiff as possible.
But the customer's request is to change it to semi-comp
to intentionally reduce the lateral stiffness.
I could have just disassembled the freewheel side
and replaced the spokes,
but since the customer said it was okay to replace
all the nipples too,
I completely disassembled the wheel.
And rebuilt it.
Ebolite hub, 28H, semi-comp pattern lacing with reinforcement
Only the nipples adjacent to the valve hole are blue aluminum ones.
This is the same as before the rebuild.
The spoke weight distribution ratio changed from
100/65% to 85/65% before and after the rebuild, and
I tensioned the freewheel side comp-style,
centered it properly
and built the wheel.
I'm confident that even with this rear wheel,
we still have better overall performance than most other rear wheels out there,
The position of the nipple end face from when it was semi-championship laced
remained as a visible mark in the rim pocket,
making the difference in thread engagement depth
caused by the spoke weight distribution difference
visually apparent.
When I've rebuilt Rovar wheels and seen the final crossing contact point shift,
leaving wear marks, and similar things,
I've never experienced the threads moving backward during a rebuild—
they always move forward or stay put.
This was a fresh surprise for me.
