I took a couple days off
to create a conversion table for the 1st ST / 2nd ST of Sapim CX Sprint spokes,
which I've been using more frequently since they became consistently available a while back
（ST stands for spoke tension）.
The 1st ST is measured using Hozan values, so it becomes H1ST.
When building customer wheels,
it turned out to be impossible to take
the 1st ST by just doing each nipple a quarter turn "while I'm at it."
With 20 spokes in a 20-hole radial front wheel,
and given the variation in tension,
I number the spokes 1 through 20
and take measurements of the 1st ST for each one.
Spokes with ridiculously low tension exist below the minimum threshold
for the wheel to function at all
（the kind of spokes you often see in partially-built wheels
that rattle and wiggle when you shake them with your finger）,
but once you tension things to a certain level, the relationship between
slightly higher-tension spokes and slightly lower-tension spokes
never reverses.
With normal wheel building, in the end you just aim for
"target tension, no runout, perfectly centered,"
but with a verification wheel, I need to maintain
virtually no runout and perfect centering from the low-tension stage onward.
↑I'm selling the byproduct wheels from this work at a special price.
The rim is AL22W, and the rear rim is not an offset rim.
The rear wheel is unrelated to the CX Sprint investigation,
but since selling just the front wheel felt awkward,
and I had another research project to work on
（it's proprietary, so I can't go into details）,
I built it anyway.
Evo Lite hub, 24H, black semi-comp 1.46 lacing pattern.
I'll tension the spokes later.
The nipples are basically black aluminum nipples,
with red nipples only on either side of the valve hole.
This is convenient for my research purposes,
not because it affects wheel performance.
Looking back, I could have just taped over the valve hole
with non-black tape. Oh well.
I haven't weighed all of them, but the rim weights
are generally around this range. The AL22W rim is listed
at 445g in the specs without distinguishing between offset and non-offset,
but the non-offset tends to be around 430g, and offset around 450g.
I went with a REVO hub instead of an Evo hub.
The Revo Disc hub only comes in through-axle, front and rear 24H,
but the Revo hub has the front in 20H only, and the rear in 16:8 24H only,
and the rear hub isn't useful to me.
The front can be a substitute if I run out of Evo Lite Hub 20H stock
（this is something I'm intentionally stocking separately;
our store's Evo Lite stock isn't depleted）.
The flange hole diameter is larger than the Evo Lite hub,
so it's more suited to tangent lacing.
The price is the same as the Evo Lite hub, but
the Revo hub comes with a quick release.
It doesn't look like a very secure type anyway, so it's not really needed.
The front wheel spokes are CX Sprint,
and sure enough, this spoke has an abnormal amount of oil residue on the surface.
You can smell machine oil coming from the spoke bundle,
and they get your hands dirty to the touch, plus dust sticks to them excessively （shown in the image above）.
Once cleaned, they feel smooth to the touch.
The CX Sprint comes in a threadless specification, but
the manufacturer normally applies thread
through forming （←cutting oil application is essential）
followed by degreasing,
and since there's no thread-forming step,
I suspect the degreasing step that follows is also skipped.
Built it.
Revo hub, 20H, black CX Sprint counterclockwise radial lacing,
With red aluminum nipples only on either side of the valve hole here as well.
This one has no performance significance and wasn't for research purposes either—
the reason was simply to match the rear wheel appearance.
I'd intended to build one spoke tangent on the front wheel,
but I ran out of time.
Since I already have four rear wheels, I need to build at least one more front wheel.
For the selling price, both wheels together are ¥44,000 (tax included).
Well, there's hardly any pre-built wheel in the same price range
with a lighter and stiffer rim than this one.
I forgot to mention—the rims are tubeless-ready.
For inquiries about stock, please call or visit the shop.
When you do, please ask for the "AL22W special-price wheels."
