Another wheel day (and so on).
About a month ago I rebuilt the rear wheel of a Reynolds rim brake wheel
Attack with a disc hub (→here)
and today I finally got around to rebuilding the front wheel.
The image above shows the state before rebuilding.
Tni makes an LW Super disc hub
designed for straight-pull spokes,
and it arrives in the same kind of mesh bag as the lemon soap
that hangs from the kitchen faucet,
but the important feature of this hub isn't that it's straight-pull
or that the hub itself is lightweight,
but rather that it's one of the rare 20-spoke disc front hubs.
Aluminum rim wheels for rim brakes
have silver brake zones
or wear marks if they're not brand new,
but with carbon rims the signs of use aren't as noticeable as with aluminum,
so there's decent demand for
"taking the rims from front 20-spoke / rear 24-spoke rim brake wheels
and turning them into disc brake wheels."
Even complete disc brake front wheels
are often made with 24 spokes,
so hand-built front hubs with 20 spokes are pretty rare.
I was thinking about creating a spoke length calculation formula
for this hub, but it turned out to be quite tedious.
If you already have spokes cut to the correct length,
building the wheel is a breeze.
Built.
LW Super Hub, 20-spoke, half CX Sprint,
forced symmetrical 2-cross pattern with spoke ties.
With spoke ties, since the final cross is close to the hub
the effect is minimal,
but when I tried just binding one point with steel wire
without soldering, there was a slight difference,
so I went ahead and did it.
↑This is the weight of the rebuilt wheel,
and if someone said they'd only tell you either this
or the weight of the rim by itself,
how many people would answer "the wheel weight"?
If you're building a wheel to deceive those kinds of people,
it's better to use full CX-RAY spokes
instead of half CX Sprint.
If there were a separate disc brake front wheel
weighing less than 570g,
that would absolutely be judged as having superior performance.
Well, manufacturers generally only provide
the same information as this anyway,
so it's probably unavoidable that it becomes the only basis for judgment.
What? The weight of just the rim?
I told you the wheel weight, so just imagine it from there.
↑Wow, that's awful.
Sorry for the wait! Please check out these images!
It's the rear rim!
It's the front rim!
↑Stop it!
