I was just at beatty park on a ride and the bead on my front rim came unseated when I landed a jump.  Scrapped up my knee a bit, but nothing too aweful, but i wanted to take the time to give props to the man who helped me tremendously and ran my bike back to my car and let me hobble back with his.  I really appreciate it! I really enjoy being home in Charlotte the riders here and mountian bike culture is awesome here!  I have been out in raleigh before and had equipment failures and walked by at least half a dozen riders who never even yeilded much less stop there ride to help someone else out.

well its usually more of a dig ride eat ride sleep repeat, but for now it'll be scratching my head on how a maxxis tire bead tore.  Upon inspect inspection of the bead I noticed there's 2 sections where the belting/threads are torn on the bead its a little disheartening because the tire had awesome grip and minimal rolling Resistance but from reviews the Ignitor tire had mixed outlooks on its tubeless capabilities.  I am not too sure of the tires history because it came on the bike used so the previous owner could've used poor lever techniques and snapped it.  I guess you live and learn though, just really glad it was close to the parking lot, and that someone was out there and willing to help.   I checked out my knee a little more and noticed some blood on my chainring I assume the bike whipped around when I laid it down a bit and I caught the business end of the teeth.  Probs let it rest for tomorrow but I should be in good shape to do some trail work at the least Friday

Your bead most likely broke when the tire blew off the rim.  I have had this happen twice to me.  Luckily for me it happened in the garage when seating the bead.

People can be b@$tards - then they can surprise you by doing something like this. It's been my general experience that most mtbers will stop and assist a fallen comrade. Just my 2 cents.
