Before getting to the main topic.
The actual measured weight of the rear wheel of the CLX 50 with rim tape.
Whether the manufacturer's stated weight of 770g includes or excludes the rim tape is unclear.
↑The weight of the rim tape.
↑I disassembled the rear wheel.
This image is the same one from a previous article.
Just looking at the hub, you can't immediately tell if it's for rim brakes or disc brakes,
but from the position of the rim logo, it's clear there's no brake zone,
so this rear wheel is for disc brakes.
↑The rim weight.
The Alpinist CLX clearly has quite a light rim,
and without even disassembling it, I could estimate the rim weight difference from the CLX 50
and the spoke weight difference calculated from the spoke length differences pretty accurately,
so I'd been meaning to do that eventually.
(By the way, Roval doesn't publish the length of spare spokes.)
But that became unnecessary.
I got the chance to disassemble the actual wheel.
So today it's wheels again (and so on).
I received the Alpinist CLX from a customer.
Compared to the Bora WTO, it has significantly worse lateral stiffness,
and worse than the Nomu Lab Wheel No. 8.
The latter aside, comparing it to the former is frankly rude.
Only Campagnolo, Fulcrum, and Corima have managed decent results with left-right mixed spoke patterns.
You shouldn't compare them.
This wheel tends to flex on flat roads and climbs, and doesn't feel efficient.
On climbs, you can tell the rim is light, "but that's it"—
it doesn't feel like it's moving forward. I think the rear wheel is the main culprit for this feeling,
but today I'm rebuilding the front wheel.
"Alpinist" is printed on the rim.
The rim depth is 33mm.
On the outer edge of the rim, there are bead seat recesses
and the edges have a reverse taper shape like a hump,
but this is a tubeless-incompatible rim.
The rim tape looks identical to tubeless tape, but
tape specifically prepared without the "tubeless" designation
is used on the Alpinist and Rapide, and that's what's applied here.
When rebuilding, it's possible to use a reverse mixed-diameter lacing
without removing the tape.
That's what I did with the CLX 50 in the previous article.
But I thought that determining the actual rim weight
might serve the public interest,
so this time I decided to completely disassemble it.
Weight with rim tape.
I peeled off the rim tape.
Underneath is a sticker saying "Tubeless incompatible."
It looks like there's a prohibition stripe over a water droplet,
but it seems unlikely that sealant moisture is the reason for the incompatibility,
so this water-droplet-like symbol might represent the cross-section of a tubeless tire bead hook interfacing.
Weight without rim tape.
The Alpinist CLX, unlike the CLX 50 and others,
has both a listing that says
Weight: approx. 532 grams (Front)
and
Weight: 562g
and I don't understand the distinction.
When I switched the language to English, they became
Front Wheel Weight: 532g
Weight: 562g
respectively, which matched the home country website.
The 532g figure is followed by 1248g for both wheels combined,
so that seems like the official weight.
Even subtracting the rim tape weight,
the actual measured weight is heavier than that.
Edit: 562g is the correct one. Details in the next article.
Built it.
I made the non-rotor side black CX Sprint.
Later I'll lace the tangent pattern on the rotor side,
but between "using the original spokes and just relacing" and
"doing left-right reverse mixed diameter but not relacing,"
I get the feeling the former would work better for this wheel.
In reality I'll do both, though.
Also, I feel like I should have posted another image,
but I can't remember what it was. Let me think...
