Another day of wheels (and so on).
Following the front wheel the other day, I also rebuilt the rear wheel of the CLX40.
In the image above, one spoke on the freewheel side is missing
because I removed it to check its length.
All-black Campagnolo Straight 2:1 lacing (XI lacing) 24H.
On the freewheel body, I found evidence of the lockring being tightened
with the top gear in the wrong phase.
The original spokes showed wear marks
at the final crossing on the freewheel side.
As I mentioned when doing the front wheel,
I had assumed that Roval rims from the internal nipple era
had no hole offset. If that were true, I was planning to
rebuild the 16+8H as 12+12H with a generic hub.
However, it turned out there actually was hole offset,
so I need to stick with 2:1 lacing and the original rear hub.
The image above shows holes on the freewheel side,
and they're centered without any particular offset to the right, but
↑the holes on the non-freewheel side are clearly offset to the left.
All built up.
Black CX-RAY Straight spokes on the freewheel side,
and mysterious square aero spokes on the non-freewheel side.
I'm not sure if spoke leading (结线) is necessary, but I went ahead with it anyway.
If this rear wheel had been Ж lacing instead of XI lacing,
I might not have done the spoke leading.
before
after
The hub shell was dirty, so I cleaned it while the hub was still separate.
The non-freewheel spoke closest in phase to the opposite side of the valve hole
had a magnet wrapped around it with self-fusing tape, so
I fixed the magnet at approximately the same position on a spoke
of the same phase using heat shrink tubing.
This CLX40 has a tubeless-incompatible WO rim
with internal nipple specification.
The current CLX50 rim is 10mm taller in rim height than this one,
has wider rim width, and is tubeless-compatible,
but the weight is about the same.
That makes it excellent in height-to-weight ratio.
It's not the case that the CLX50 is lighter because it's a disc brake rim—
the current CL/CLX50 rims have the same weight whether they're for rim brakes or disc brakes.
As for the specific measured weights... why would I tell you that?
↑wow, what a terrible attitude
Sorry for the wait! Please take a look at this image!
It's the front rim!
It's the rear rim!
↑stop it!
