This is interesting. According to China Cycling, DT Swiss has come out with a hub that takes carbon spokes. Does anyone have more info. on this?

Not only that he said DT Swiss has come out with their own carbon spoke range, so it appears it isn't only the hubs. Happens at the 11 minute mark in the video.

So Light-Bicycle stop trying that idea and only keep making oversized version which require special hub since.
So is this why LightBycycle stopped assembling custom wheels on carbon spokes and only sells “their” carbon wheel sets?
As far as I know. Yes they stopped assembling wheels with carbon spokes which fit every hub.
But they keep the oversized carbon spokes which require a special hub.
But I'm not Light-Bicycle, you can ask them. Maybe they could still build one if you somehow want the discontinued spec.

I interpreted that as hubs that can take carbon spokes, not carbon spokes itself. I guess we'll find out sooner than later.

Does anyone know the weight savings between the LB oversized carbon spokes vs. Sapim CX-Ray?

369g for the pair, seems kinda porky, equivalent to DT350

That's too bad. The extra weight negates the lighter carbon spokes.

Is there any comparison between carbon spokes and Spinergy's PBO? stiffness/weight for example

I have been using the carbon spokes branded as EIE / Nextie / Brisk.
They are from one factory.

The "oval" model is 2.3 x 2.0mm, and in regular lengths (around 290-300) average 2.3g each.

The thin model is 2.3 x 1.6mm, and those average 1.9g each.

CX-Rays are well into the 4 gram range. But these carbon spokes have more tensile strength,
due to the unidirectional layup. So the advantages are many IMO.

THB I have not tried the LB ones. Before I bought any carbon spokes I ruled out the heavier ones,
including the bladed versions at 3.2mm wide x 2.0 thick (or thereabouts).
Carbon comes in all shapes & sizes these days.
But the LB ones would have to be around 2.5g I would guess.

Nextie have an interesting new spoke design, too bad they only make spokes with interfaces for regular straight pull hubs

https://www.nextie.com/carbon-bicycle-s ... ro-NXTCS06

Tensile strength nearly identical to cx ray

That's a really intresting spoke. It even has shaping beyond a elispse.

I saw this. Spoke looks very interesting. But I still don't think normal low flange road hubs are a terribly good idea with carbon spokes.

Seems like just a worse version of the vonoa spoke tbh. It's not even a taperlock design so more prone to failure. The trailing edge doesn't seem like it would carry any load and it probably doesn't cause the spoke isn't very streong.
