Replacing broken spokes on Roval Control SL, on the trail

This wheelset (29mm IW, I believe) came with a 2021 Specialized S-Works Epic EVO I bought used. Last week I broke a spoke near the nipple, just riding along, not even hitting anything. This got me worried since I'm planning to use this bike/wheelset for a long backpacking race in a few weeks, with little access to bike shops. I know it's not the ideal/recommended use for this wheelset. I was planning on building/using a different bike but for a number of reasons this is what I have now.

I called Roval and they gave me the specs of the spokes: DT Swiss Aerolites, bladed, straight pull, T-head, 294mm, 14 gauge. Both wheels use the same spokes on both sides, which is cool. These go into DT Swiss 180 hubs.

Assuming I can get replacement spokes and nipples (not sure which!), how do I change spokes on the trail? I've been looking for videos but I don't think what I've found is applicable to this specific wheelset. I'm guessing I need to take out the rim tape, get a new spoke threaded in the hub, and crossed properly, looking at the rest of the wheel, insert a nipple on the rim and start threading the spoke making sure the flat side is aligned to the other spokes. Then I'd use a tool to prevent the bladed spoke to rotate. DT Swiss is the recommended one (big, metal) but that's too heavy for carrying on the race, I'd take the less-recommended Park Tool BHS-4 (small, plastic). Then I'd put a tube in, or maybe carry enough 3M stripped tape to re-tape the wheel, rolled onto the pump. I've used that in other wheelsets with Stans and it has worked well.

I'm not concerned with leaving the wheel perfectly true. I just want to make sure I don't have wobbles bad enough that the tire rubs on the rear triangle, or anywhere else. The idea is to be able to ride to a bike shop (3 in 540 miles). Also, I'm worried that several of them might fail in one stretch between bike shops, so I'd carry 3-4.

Any comments, recommendations or resources to check?

Thanks!

If you break a rear spoke on the trail you are not going to be able to replace it unless you also are planning on bring the necessary tools to remove the cassette. A better solution and one that I have tried is a temporary spoke from Fiberfix. Amazon.com : FIBERFIX Emergency Spoke Replacement Kit. : Bike Spokes And Accessories : Sports & Outdoors . I works quite well.
Here is a video on how to install.
Thank you, I thought of carrying that for my previous wheelset. This one has a hub with straight pull holes/spokes, so I wouldn't need to remove the cassette. I can just slide the spoke into the hub hole and thread that into the nipple. I've even seen a video of a Shimano hub/wheelset where the nipple goes over the spoke (also straight pull) and then the nipple threads into the rim (the nipple seems to have an external thread). In that case you don't even have to deflate the rear tire! That's not my wheelset though.

In any case, I guess this Fiberfix could work on my hub, although the cord seems much thicker than the tiny hole in the hub. I'll look into this.

Thanks.

You don't need to remove cassette or brake rotors to replace spokes on your wheelset. That's the beauty of straight pull spokes on DT hubs. If nipple is reuseable then weave in a new spoke, tension, true, and keep racing. If not, cut a hole in the spoke tape and remove and replace the old nipple first. Afterwards clean up the area around the hole in the rim tape with a single use alcohol pad. Patch the hole with Gorilla tape. Then continue on. If you're carrying a lighter, you can heat up your old spoke and use it to melt a hole in the rim tape above the nipple you want to remove instead of trying to cut a hole.

Great advice! The nipple on my broke spoke "disappeared" but I think now it might have dropped inside the rim. I did shake it and didn't hear anything, but I didn't cut the tape since I didn't have anything to replace it with, and the wheel was true, so no need to fix it right then.

I do carry alcohol pads and Gorilla tape so I'll do that. I wasn't planning on carrying a lighter for this trip, but good to know about this for other trips. Now I need to get the right nipples.

Thanks!
