Excuse the rookie question, but can someone please confirm the lacing of this wheel (not mine), is it x3?:

Ya think you could take a pic where the rotor isn't covering the area of interest?
Sometimes a bit of thought can be useful.

Lol I did not take the pic, it's from the web, plus an area of interest is subjective, it so happens mine and his aren't the same...

Here's another one, perhaps x2?:

It'd be quite difficult to lace 24 spokes more than 2X.

Interesting that the wheel builder/manufacturer decided that interlacing the spokes was unnecessary. Might be nearly impossible to do, at that, given that hub design and the use of such heavy-gauge spokes.

Might want to rethink that setup.

i agree, 2x.

Seems like the kind of hub meant to be built with bladed spokes only (to facilitate interlacing)

The welding on those brake mounts looks downright scary.

2X with straight pull spokes. 24 spoke wheels are almost universally 2x although I have seen a few done 3x. (J bend only) With straight pull, you don't get to chose the pattern as the spoke holes point the spokes where they want it to go.
Straight pull wheels are often not interlaced. I build as many straight pull as J bend these days, and I do interlace when it doesn't cause too much distortion, but don't sweat it if you can't.

Those spokes look way too beefy. That wheel will have no elasticity, and be prone to fatigue failure and spoke unwinding unless there's a hell of a lot of spoke tension.

...Hang on, that wheel is tiny. Is it less than 20"? Are those 14g spokes? Even so, butted would be nice, although I guess very hard to find in that length.

That looks like a Brompton Titanium Fork. It appears that the welds used for the add on disc brake have cracked.
You say Picture from the web, I hope they are explaining what they did wrong and are not planning to ride it.

Yep a 16" wheel, likely a proof of concept, when I look at the owner's more recent pics that particular fork setup is not being used.

On a related note, can someone please help me interpret this pic? I'm trying to determine the hub's spoke offset:

Nothing useful there for determining spoke offset. try this.

Awesome many thanks!

Note that it says the hub manufacturer should give you the offset but more often than not, I have to determine it on my own. That means trying to determine where the center line of the hub passes through the post, inserting a spoke of a known length and measuring how much spoke protrudes.
