Ok I will get you some pics of the damaged eyelets and rim surface. I see what you mean for the cracked rim - those two spares I have were found in a bin after a 24h race and never used since, but I pulled a spoke a few years back on one of my front crossmax when a log jumped out at it, and the rim did crack (I have been running it on 25 spokes since!). For those two rear I have, I don't think the rim is actually cracked - maybe slightly deformed. My guess would be, If you are not too heavy, that you could run a rear wheel with that particular spoke not too tensioned in order not to damage the rim/eyelet anymore. The rim is plenty stiff (I've never had a problem with the front on 25 spokes, despite the big gap between two spokes). That's just a fix I guess and up to you if you can be bothered to rebuild a wheel with a rim that is not 100% ok. What was the problem with your rim? Ceramic dead?
