Another wheel day today (and so on).
I accidentally deleted the before-rebuild photo with a camera operation error,
so this time I'm jumping straight to the after-rebuild image.
I received a set of front and rear wheels from a customer
assembled on a Prime 38mm-deep carbon tubular rim
for rim brakes.
Dugast cyclocross tires were taped on,
and since there was a feeling of slippage in the corners,
the customer wanted both wheels rebuilt with a tighter, crisper feel.
The hub is a Prime brand straight spoke 20H hub,
and I changed the spokes from black aero-lite straight
to silver CX sprint and tensioned them as tight as possible.
The tubular tape is
Caronya (product name) by Effetto Mariposa (manufacturer).
Effetto Mariposa is famous for their sealant called Caffélatex.
When you peel off tubular tape,
residue can remain on the rim or the tire,
but with this tire it mostly stayed on the rim.
I say "with this tire" because
whether the tape residue remains on the rim or tire
is largely determined by the tire's specifications.
In the case of Continental's German-made
tubular tires (other than Giro made by Lion Tires)
with black cotton base tape, when using Miyata rim tape,
residue almost always remains on the tire side and
is bonded so strongly that removal becomes virtually impossible.
With tires like Vittoria and Veloflex,
which seem to have wax applied to the base tape,
the tape tends to separate cleanly.
On the rim side, once you peel back a certain length,
if you then carefully pull the rest, it can be removed cleanly.
The tire side had only this much residue, but it came off cleanly too.
Of the two images above, the upper one is 1920×1080 pixels in 16:9 aspect ratio,
and when compressed, the long side is set to 640 pixels,
making it 640×360.
The lower image is 2592×1944 pixels before compression in 4:3 aspect ratio,
and 640×480 pixels after compression.
I wasn't happy with the white balance in the lower image,
so I changed shooting modes and later realized that
image size settings are saved separately for each mode.
Also, there's a "macro shooting mode" that allows 1cm close-up shots—
a kind of automatic mode—where you can only select
image sizes from the 16:9 options, but
from the "Program mode" where you can set detailed parameters,
if you select the 1cm macro focus setting,
you can choose 4:3 image sizes. I discovered.
The subject being photographed is a DT black aero-lite straight spoke with a "DT" marking on it.
I've always used Sony digital cameras until now,
and I stuck with Sony (or rather, couldn't leave) because
I was familiar with how to use them and
could maintain battery and charger compatibility.
But since no successor model has come out
and cameras in the same price range as what I've been using lack strong macro capability,
after considering various options, I bought a Ricoh digital camera.
Effetto Mariposa's Caronya, and
the upper right in the image is Miyata's tubular tape.
Miyata tubular tape is currently out of production,
and while they haven't explicitly said they're discontinuing it,
enough time has passed that it could be interpreted
similarly to magazine suspensions (which in most cases means permanent closure).
The circumference of a 700C tubular rim excluding the valve hole
is approximately 1970mm (→here and its link).
That's roughly 2 meters.
Miyata tubular tape came in 16mm width / 20m rolls
at a retail price of ¥3,500 before tax, so one application costs ¥350.
Caronya comes in 2m and 16m rolls;
the 2m roll is one application, but
pricing varies by width at ¥2,400–¥3,000 before tax,
which feels extremely expensive compared to the cost of tubular tape.
The 16m roll is eight applications, priced at roughly ¥10,000–¥13,000 before tax,
so one application costs around ¥1,500.
With the tubular tape, we only have
an opened roll that we use for shop work,
and even though the one in the image has been used three or four times,
even accounting for that, the core diameter is nearly the same, yet
the overall diameter is larger with Caronya
because Caronya is thicker.
When Miyata tubular tape is used for cyclocross, the tire can slip sideways or even come off in the worst case,
but according to the customer, they've never had Caronya come off.
However, since they apply aqua-seal to the tire side, especially at the rim interface,
to keep the base tape dry and protect it from mud,
they weren't sure what would happen with Caronya alone.
With Caronya, we're aware of the high price and
the fact that if the rim has a shallow profile, the white tape is visible from the side due to its thickness,
and we use it at our shop as one successor option to tubular tape.
Currently at our shop, we only use tubular tape
for re-taping tires that were originally taped with tubular tape.
The second successor candidate
is TUFO's gluing tape.
This existed long before tubular tape went on hiatus.
It's so strong that it won't come off even in cyclocross,
and the tape is three-layered with a specified direction for rim and tire sides,
but when you actually change tires, the tape often remains strongly on the rim side,
and considering the hassle of removing it each time,
frankly, rim cement is easier.
So I don't recommend it.
The advantage that you don't have to worry about drying time
and can use it immediately after application is a strong point for tape, though.
The third successor candidate is ICAN (I-Can),
but we don't carry that at our shop.
Apparently it's thin and cheap.
