yup done that in the garage on my 29er... it's made me a little nervous every time since (and this was years ago)... sounds like a gun shot... i'm always very careful to check the bead now lol...


as for co2 and pumps... I picked up this oddball from nashbar years ago http://www.nashbar.com/bikes/Product...2_172872_-1___ it works as a hand pump or you can use 12g co2 treadles cartridges (I had tons of them from my paintball days)... I used it out on the trail a few times, the 12g got me enough air into the 29er tire to not be take 2 weeks to pump it up the rest of the way by hand...
