Count me among those that experienced a flat on their first real ride on this bike.
I tooled around on the bike in the driveway a bit previously, but last night was the first time I took it out for a real ride. I flatted a couple miles from my house. I knew of this issue that others have had and even ordered some rim tape that should be arriving tomorrow, but I risked it anyway and it bit me.
I was in a hurry to get somewhere and grabbed the bike without much thought (and without a flat repair kit). I was only going a few miles, right? Needless to say, I was late for where I was going since I went ahead and walked the rest of the way there and ended up walking the whole way home late last night. :-(
I have not had a chance to inspect the wheel yet, but I presume it is most likely the exposed spoke nipple issue.
