Check your Javelin tubes and rim tape!

You know what they say about the ol' -u-me thing, don't you? Sounds like you had pinch flats, the primary cause of which is under-inflated tires. Not sure if your LBS checked your tires, or how much time elapsed between the tuneup and the race, but perhaps in the future check your own inflation prior to the ride.

Did you check your inflation that morning?  You should always air up your tires or at least check the pressure each time you ride.  Underinflated tires + cracks/rail roads/holes = pinch flats.

That being said, I experienced a flat with properly inflated tires recently.  After hearing about other P2C owners getting flats left and right, I checked out my rim tape.  The stock tape was the plastic kind with no adhesive backing.  When I took the tires and tubes off, it was obvious what had caused my flat -- the tape had shifted all over the dang place and some of the spoke holes were exposed.  A few bucks worth of cloth tape and problem solved!  Hopefully.

I talked to Dave at Javelin when I purchased my Sizzano and he actually suggested that the first thing to do with these bikes was to put new tubes in them since they had been in storage for a while.
