Learned a Lesson About New Wheels

I bought some new wheels a couple of weeks ago.  Put em on and have done a few rides.  Got my first flat today.  Went to put on the spare tube.  Ooopppps.    The valve stem is too short.  Couldn't fill up the tube with CO2.  

Fortunately, the guy I was riding with had a long stemmed tube.  So we finished the ride ok. 

Lesson: Make sure your tubes fit your wheels.
