Some of you know I am a pretty big fan of Campy wheels. Have ridden them for years dating way back. That is until yesterday.

Yesterday was very different than anything I have ever experienced and I have been at this a long time. It was Mother's day and so wanted to get a morning ride in knowing I would consume a lot of calories later

so headed out to my usual cycling road I ride for a quick blast. Got out there...catch a wheel of a sporty rider and we take turns pulling and having good conversation and we part ways about 10 miles out and I am heading home and boom, rear tire blow out. Hadn't had one in a while....have had great luck with Rubino Pro III's and standard heavy butyl tubes. So, stop to do the usable thing. Wasn't under too much time compression and carefully inspected the tire to make sure a thorn or something else like glass wasn't lodged in it...couldn't find anything...quickly checked the rear wheel, back together...tire inflated with CO2 and back on the road and then 1 mile later and boom...another rear tire blow out. Well, when lightning strikes twice something more than coincidence is at play but unfortunately I was SOL because I don't carry two tubes...at that point rely on a riding buddy but I was out for a quick solo blast and I either had to walk home or catch a ride. A word about human nature. It is not unlike this forum which is kind of a microcosm of society. The vast amount of people out enjoying a perfect day will do so much to help anybody in need they can and of course there is subset that will never offer to help. When I see somebody down, I always offer my phone or will donate a tube or inflator if it will get them back up and riding home. Of course many won't. Yesterday as it turns out I passed two rather nice looking girls on my way home and as I went I by...they were gabbing a bit on their road bikes and they laughed and said they just felt like gossiping and not riding harder to keep up and we all had a laugh about it. So now stranded, since I went down twice, they caught up to me and asked if they could help and I said, well, do you have a spare tube? I could take your name and be sure to return the favor. The girl said, well yes, I have two tubes and will give you one. Wow. Somebody I didn't even know would offer a 3 dollar tube. She didn't want to exchange contact info and simply said, nah...I will see you back out here...and you can repay me then. How kind people can be. Countless people stopped in fact...couple of other girls stopped and said they were glad it wasn't them because they wouldn't know what to do...and some great guys offered to help including one of my group ride buddies who was out there.
OK...enough. I am thinking...2 tubes in a couple miles....has to be an issue. There was. This time I very closely inspected the tire and rim which leads to a question as there are lot of wheel experts on this forum and I have never seen this in all my years of riding. A burr inside the rim where the seam of the wheel comes together had developed that was protruding through what looks like an integrated rim tape that was poking thru and popping the tube. The wheel seam from the outside of the rim looks normal. But on the inside, where the seam comes together, the two sides meet almost convex...with a bit of an edge which was repetitively popping the tube. So what to do next? I had a short segment of tube in my seat bag and I thought I would place this over the sharpness and buffer the tube. Best laid plans. So put that in there, inflated yet another tube with my last CO2 canister....got the wheel back on and was flipping the bike back over...and boom....lost the tube that the nice lady donated. Now I am really screwed. Since I was 5 miles out and in cycling shoes, I had to call my girlfriend to come pick me up. Its been several years since I have had to call for a ride in fact.
So...what do you guys think? I had never experienced this. These wheels are just a year old and I have put 20K miles easy on previous Campy wheels. This is the latest and greatest redesigned Fulcrum 5's...still have another set of Fulcrum 5's in operation without issue.
Fulcrum isn't easy to call...can't find a phone number for their customer service in North America. If any of you guys have a contact, please let me know. I did find an email form on their website and just wrote to them for direction...either warranty or do they suggest dremmeling the high spot of the interior rim seam down smooth and then say wrapping the rim with Velox rim tape to cover the seam?
I don't want to lose the wheel but if this happened to me, it probably has happened to others with these wheels...I am no Clyde nor do I jump off city curbs. Design onesy's as it turns out are quite rare. Design and manufacturing are like DNA. If there is one out there, there are generally several.
Any advice is welcome and appreciated. What would you do in this situation?
thanks
