Carbon Fiber spokes? Is this a thing?
Happened to come across this newish listing on Hunt's site. What's the verdict on using spokes made with carbon fiber instead of pedestrian steel?

I think CF spokes have been around for quite a while.
The fact that they haven't really hit the ground running tends to show, in my opinion, that they're not necessarily fixing anything that needed fixing, or not offering that much of an improvement over steel.
I'm also wary of Hunt's marketing, in general.

Most of the carbon-spoke wheels I know of (like the Lightweight brand that noodle soup mentioned) have the spokes baked into the hub and rim. You can never true them, but the idea is that they may never need to be trued.
The wheels in OP's post use a nipple setup, which is...something. I'd hate to be trueing one of those wheels and hear the sickening crack when the nipple rotates the spoke beyond it's malleability limits.

I had a pair of Mavic Cosmic Carbone SLRs that used carbon spokes. They were carbon bands that stretched across the hub, rather than connecting in to it. You could true those wheels. And I think Spinnergy or Toppolino had carbon spoked wheels 10 or 15 years ago.
But yes, the Mavic R-Sys with the round tube spokes had issues.

"UD CARBON SPOKES
Incredibly strong (achieving over 450kgf per spoke) TaperLock UD carbon spokes offering 30% increase in stiffness against steel ones. Only 2.7g per spoke. Due to the TaperLock technology, these spokes can be trued easily using a spoke key from within the rim bed."

The Spinergy SPOX wheels used a kevlar spoke. I remember the rep showing me that he could tie one of the spokes in a knot. They never really caught on in the road market because of how aerodynamically infeasible they were. Turns out, 28 flexible 3.5mm-wide cylinders flying through the air (per wheel) caused a whole heck of a lot of drag. I raced with a guy back in the early 2000's that ran them and you could hear the spokes beating the air to death underneath him, and he claimed he could feel them "humming" at certain speeds, but especially in crosswinds.

Scott makes a MTB wheel with carbon spokes. Though, as others have mentioned, unlike the Hunt wheels, the spokes are molded to the rims and hub shell. Still, Scott are putting these wheels under their World Cup XC racers, meaning they must think the carbon spokes will hold up to much harder riding than an average road wheel will ever encounter.
On the topic of wacky spoke ideas from the world of MTB, they are now building wheels with spokes made out of Dyneema thread. Somewhat surprised not to have seen this appear on road wheels yet, but assume that has to do with aero issues. Though it looks like they are pitching to the gravel crowd.

Flexiest wheels I've ever ridden by a LONG shot. I demo'd a set and made it about a mile before handing them back and showing the rep the rubbed paint on my chainstays.

To pile in on this, we’ve also got Winspace, corima, cadex and partington, just to name a few. Bikeahead makes carbon monocoque wheels, but that’s not the same thing.
Cadex is a fairly big brand in that it’s Giant’s in house brand and their wheels will be OE on top end TCRs for the next gen. So I imagine they have the whole assploding thing figured out. I believe Cadex and Winspace, just like hunt, have independent replaceable spokes. Corima, just like the R-SYS, use pillar spokes a la wagon wheels. Partington uses baked-in spokes like LW.
My take on this is that people are totally right to be skeptical of these, and we may never figure out how to prevent these from failing suddenly and catastrophically (that’s just how carbon works) but from what I understand about carbon fiber, there is hardly a better application for it than tensioned spokes when it comes to performance.

I have some Mavik R-SYS wheels, post redesign after they were strengthened to resist the kind of failure shown above.
The spokes are tubes that work in compression and tension.
Light and stiff, but just about the most un-aerodynamic wheels you could find, depend on proprietary little bits, and developed creaks.
Very Maviky.

The externally-threaded nipple was a neat idea, but you've gotta put linseed oil on them every few months to get rid of that damn creak. Same with where the spoke meets the hub.

I used oil at the hub, which wiped out some little (paper?) washers in there & made the creaking worse.
The LBS said they could send them to Mavik to be rebuilt for a mere $1k.

I'd just like some more good options in the vein of the H3.

I love Mavic shoes and clothing, but their wheels are a bad joke.

Those Hunts look pretty sweet. The spokes are a decent size, so no aero penalty by the look of it. The ends seem well done; I like the square bit to grab the spoke with to eliminate torsion. But the filament-wound rims seem just as impressive. These wheels could be pretty nifty, if they live up to the marketing. Although the weight doesn't seem too impressive; they'd want to be super stiff, or what's the point.

EDIT: I don't want to come off as a shill for Hunt, but came across a couple things as well for those concerned with possible breakage and warranty service. Lifetime free crash replacement and servicing, and, Hunt now evidently has an office/service option in Boulder CO (so don't need to ship to the UK):
