I have a rear wheel with a 29" WTP STp i25 rim. The rim is irreparably damaged, but the wheel is otherwise in good condition. The spokes are not affected, the hub is great, and the wheel was pretty new when it was damaged. It's been hanging in my garage as I mull over what to do with it. I think I'd like to rebuild it. If I could find an identical rim, I would (in very broad strokes) just need to undo the spokes (probably tying them together in such a way as to make the rest of the job a little quicker), re-lace onto the new rim, dish/tension, retension, voila!
The problem is that I can't find another one of those rims. I can find a couple of i29 rims, I think, but not the i25. So, my question: For my brilliant scheme to work, don't I just need another rim with the identical ERD? Or is there more to it? My goal is to repurpose as much as possible of the current wheel into the new build.
