R I P my trispoke 😒
Yup, well I got it for a decent price last year then used it for a while and then didn't pay attention to it. I am now ready to finish my 2.8 project and noticed a idiot I know damaged my Specialized front trispoke. I'm running it tomorrow, think its trash already or it'll run ok? 😑😩😡

I wouldn't ride anything that was damaged carbon fiber. That said, I had a relative who smoked two packs of Camel non filters a day, they finally killed him when he was 96. Maybe you'll have his good luck but when it comes to something supporting my body weight at speed; if you have to ask, the answer is NO.

That should be repairable assuming similar to how carbon fiber frames are repaired. I don't know what the cost would be.
Appleman Carbon Fiber Repair
This is not an endorsement, I just did a quick search. There may be other out there that can do the repair.
If it were me, I already have West System Epoxy and might even try it myself.

To repair that rim, I'd want access to the inside of the rim and run fibers lengthwise from well before the damage to well after so there was plenty of contact for the secondary bond. Cleaning, sanding and laying that fiber inside the rim would be a challenge. Might take an early morning lying in bed insight.

You could also contact a university near you that has an architecture or engineering department and ask for some tech. support. Many of my students are working with CF.
Best, Ben

I used that epoxy and a scrap of unidirectional carbon fiber someone gave me to repair cracked chainstays on a steel bike. (It was hit by a car, Both were cracked for a total of a full revolution). I put 8000 miles on that frame after the repair. Retired it because I didn't know what other damage might have been done. Repair stayed rock solid. Stiffest BB'd Peugeot ever.

The balance is a secondary issue that might become an issue once or twice at 45 MPH. The rim staying whole, especially at that speed is primary. And you can always epoxy in some weights opposite to balance.

To me, the uncertainty of the condition of the wheel plus the certainty of injury, perhaps catastrophic injury, if it fails makes this a no brainer - ditch the wheel. Not a close call. Far too risky to do otherwise.
Additional factor - there is never a good time to need to be in the ICU. Now is a really, really bad time. As in, there might not be a bed for you.

Sincerely, its a hard thing to drop the rim just like that. Its a Specialized vintage trispoke in a vintage stiff frame. So i'm starting by getting in contacts with people and see if it really can be repaired, like better than before. I hope its possible, if not ill sell the pair sadly. The pair worked perfectly since I got them, they're pretty heavy tbh but the look cover that. Got them for $290 from a open air market😢

Start by assessing it. They look like strong wheels and not delicate. It's a wide blade and there are no sharp corners.
Clean it up with sandpaper or a sharp knife or a dril . Leave a good clean radius Get rid of the damage. That will have to be done anyway for a repair.
How did the damage happen?
How does that spoke feel around the the damage and further out from it?
How does it compare to the other spokes?
Can you flex it?
Is there any other damage on the wheel?
Whats the brake surface like?
What are the hubs like?
Are the wheels already well worn?
It may not even need a repair
If it was me and I had satisfactory answers to those questions I would probably ride it slowly for a while and see how it went. Keep an eye on it.But that's me and I am used to doing inspections.
Certainly repairable if needed.

I had a Rev-X on the front of a Guerciotti fixed gear that was my messenger bike in the late 90's. It was given to me by a friend who put a chip in one of the fork blades, and he was afraid of it. I rode that thing for a good 2 years until I T-boned a car and turned my frame into a taco. The wheel was still straight, so I put it on a Masi, and rode it for about 6 months more before the rim wore through from braking in the rain for years. Best wheel I've ever had. I'd love to get another one, but I worry that the 25 year old carbon would have become brittle by now. If I find a good deal on one, I'm totally buying it though.
