Another day on wheels (and so on).
Continuing from yesterday.
Rebuilding the rear wheel with Prime's 28mm high carbon rim.
RD020 rear hub, 24H, all black components
Built 44-spoke Italian lacing (not JIS lacing).
The tension on the freewheel side is basically maxed out with perfect centering,
so I can't tension the non-freewheel side any further.
In terms of accuracy, it's built well.
As tight as the physics allows.
But the non-freewheel side still feels loose... hmm.
As I wrote yesterday, the final cross on the non-freewheel side is
not woven.
As for spoke length,
Freewheel side
Non-freewheel side
Freewheel side
Non-freewheel side
Freewheel side
Non-freewheel side
The freewheel side is slightly longer, the non-freewheel side is too long,
and I'm using the spoke threads all the way to the end.
Or rather, the fact that left and right lengths don't match in the first place
just shows the original calculation was sloppy.
The freewheel side needs a slight trim, the non-freewheel side I won't use.
There's a handwritten arrow saying "build with the freewheel side this way."
It doesn't look like an offset rim by any means,
and I don't see any directional difference in the hole drilling either,
but there's no reason to go against it, so I build it according to this.
Built.
Black half-component 46-spoke JIS lacing with nipple wraps.
Before
After
The reason it's lighter is the same as yesterday.
Reason #4 for taking it apart carefully is that
the customer asked me to weigh the rim for them.
You might think that to weigh the rim you'd have to take it completely apart anyway,
but any one of reasons #1-3 would already be reason enough
for a complete teardown.
For example, even if the spoke length were appropriate
and had nothing to do with the frame,
I'd still do a complete teardown
just because I wanted to apply silicone grease.
As for that rim weight, I'll report it to the customer.
I have no intention of telling you readers.
I don't see any need for that.
↑Man, what a jerk
My apologies for the wait! Please take a look at this image!
Front rim!
Rear rim!
↑Stop it, stop it!
