Can anyone explain this to me?
I ran across this photo of a wheel for sale on CL . It has what looks to me like twisted spokes. I’ll be the very first to admit I’ve not even come close to seeing everything bicycle related and this is a first for me. Is there any advantage to this or was it a dumb attempt to be stylish or different ?

There was a brief moment when these kinds of twisted-spoke wheels were cool, as part of the fixie craze of the early 2000s. There's not a whole to say about them except that they're visually unique; I recall reading an analysis somewhere showing that twisting the spokes that way doesn't significantly strengthen/weaken the wheel, it just complicates the build and truing process.

Thanks ! when I saw this I was like WTH ? Just looking at it , kinda gave me the idea it did not add strength . It is crazy looking though

No functional advantage; just cosmetic bling.

If you accidentally buy spokes that are too long, you might have to build the wheels like this so they will fit!

The problem that I've encountered is this: you twist the spokes together before you tension the wheel, so when you bring them up to tension you'll almost certainly end up with more tension on one side of the twist than the other. The overall tension may be right, but it will be too low in some places. As a result, the spoke will cycle in and out of tension as you ride, resulting in metal fatigue and (soon!) broken spokes. At least, that was my experience.

There was a British firm in the early 1990s, Simplon Titanium, that was building twisted spoke racing wheels. The claim was that the wheels were laterally stiffer, equivalent to wheel built with a hub having a 20cm flange diameter. The magazine which tested them thought they felt like a good quality stiff wheel but not outrageously stiff. However, they were built using titanium spokes, which are not as rigid as steel. Basically, they were saving 70g per wheel, while retaining comparable stiffness. The magazine did mention that there was one pro team taking them under consideration.

The OP's photo look as if they ran out of spokes and used clothes' hangers.

"You want that built crow's foot?" was sort of the standard joke when some customer you knew well brought in wheels for a rebuild.

Yup. Well, more likely I went to the bin of used spokes and they're all too long and I don't have the patience to order the right ones.

The crow's foot pattern predates that twisted spoke stuff and is a different thing. It was sort of a combination of radial and normal spoke patterns, and the spokes simply crossed each other -- no twists. Goes back to the 70s, if not earlier.
"You want that built crow's foot?" was sort of the standard joke when some customer you knew well brought in wheels for a rebuild.

I've actually never seen another bike in real life with crows foot laced wheels.

I built one today.
I damaged an old rim but I wanted to keep the DA hub. I took the whole thing apart and used the spokes off it. The new rim has a little smaller ERD so the spokes wouldn't tension up.
I unlaced it and put in a twist. I managed to do it all during my toddlers nap. I stress relieved it a few times. I retrued again once I mounted the tire. It's fine. I did this 20 years ago with ti spokes. I don't recall it being difficult then either.
I'll check it after a ride a couple more times.
This is a spare wheel to my gravel bike, mounted up with road wheels, and almost exclusively used for dragging the previously mentioned toddler around in a trailer.

I think you guys need to have been between 16 and 23 in the late 90s. Otherwise, this isn't a great idea.
After this build, I am about to change into plaid shorts and a flannel shirt. What the hell happened to all my glorious hair?

I always compared it to a poor mans's way of tying and soldering. Also remember when the bike shop guys started doing it with all of the builds claiming more strength. It didn't work when the guy who could destroy a wheel in less than a week got one. He destroyed that one too! Smiles, MH

Rosey,
We figured out that tying and soldering didn't do anything for wheels back in the late 70's other than making the spokes more susceptible to breaking at the soldered joint because of the heat and the wheel wasn't any stronger. I think that the thought process was that there would be a second section of the wheel that was tied together with the twisting that would make the wheel stronger. I found there was way too little tension in the spokes to hold them in place for stronger riders and abandoned the idea. The wheels look cool but don't have any more strength to them. Smiles, MH
About yer hair and the plaid clothes; Keep the clothes and join the hair club for men! Har!

Reviving this thread as I picked up an vintage GT MTN bike with twisted spokes and it was my first time seeing this type of build. I did know about the tying and soldering attempts from back in the late 70's.
Wheels still seem very true so the twisted build has survived well.
rosefarts RSM thought you all may enjoy seeing
