Wheels again today (and so on...).
Continuing from yesterday.
Rebuilding the rear wheel of the Vision Metron 40 LTD.
Just like the front wheel, the spokes are heavily rusted.
Rebuilt.
Vision hub 21H semi-black CX Sprint
2:1 lacing, equivalent to forced 4-0, no lacing ties.
As a counterpart to asymmetric left-right lacing,
this is reverse asymmetric lacing with different diameters,
so the CX Sprint is on the anti-freehub side of the fewer-spoke side.
As for lacing ties, since the final cross is close to the hub flange
the effect is minimal,
and I judged it unnecessary, so I didn't use any.
I'm confident this wheel will run better than the original.
Before
After
The entire right side of the rim had chain oil splatter stains.
Sometimes this is impossible to deal with,
but with this rim I managed to remove almost all of it
from both the carbon section and the sticker section.
The yellow circles in the image above are reference marks
showing the same location on both images, as the rim pattern is identical.
It's not apparent from a direct side view,
but the spoke head lateral positions on the hub flanges are not the same—
The spoke heads on the porcupine side are outward,
while the spoke heads on the anti-porcupine side are inward,
↑So the first cross of 2-cross lacing looks like this.
By the way, with this hub,
if you need to replace a spoke on the anti-porcupine side,
you need to temporarily remove
the porcupine-side spoke that overlaps at the first cross.
The next cross, which is the final cross on this hub,
you can choose whether or not to lace it,
and since the original wheel had it laced,
I also laced it when rebuilding.
For this Metron 40 LTD front and rear wheels,
square aero spokes with identical spoke weight ratio
were used on all left and right flanges of both hubs.
Because they were badly rusted,
I didn't investigate the spoke weight ratio,
but if instead of a complete spoke replacement,
we were doing minor repairs with OEM spokes—
say replacing one to a few spokes—
while awaiting those parts as a temporary measure,
if mixing in Sapim spokes,
I would need spoke weight ratio information
to judge which is more appropriate: CX-RAY or CX Sprint.
I had no interest in spoke weight ratios,
but I did have interest in rim weight, so I looked that up.
As for this information, I judge it unnecessary for
the readers of this blog,
so I'm not going to tell you.
↑Wow, what a jerk.
Sorry for the wait! Please take a look at this image!
Front 18H rim!
Rear 21H rim!
↑Stop it!
