This was my first ride with the race wheels on.  Everything went well until I ran over a screw and punctured my tubular tire.  This would have been a minor inconvenience under normal circumstances, but I didn't bring a spare tire.  I was in a rush Blah Blah.  Lucky for me my folks live about a mile or two from where I was.  They are retired and always in the mood for some excitement.  When I got home I tried a can of Vittoria Pitstop on the tire to see if the stuff would seal the hole.  It didn't.  The directions are pretty bad on the can so I went in and did some internet research and tried another can.  Nope.  If you have been thinking about carrying this stuff instead of a spare I would reconsider.  It might work with a different type of puncture, but a screw/nail hole is a common flat.  Anyway, I was off to Performance for some new tires and they luckily had a really good tubbie for $60 marked down from $80.

The tires were folded up nicely and I was able to fit the tire, one tire lever, 2 CO2's, and the inflater in my saddle bag!  Problem solved.  Don't buy Zipp Tangent tires because they don't fold flat.
