Well, I only got 50 miles on my new UFO Stealth Jets and have my first
flat. Damn! I hit what I would consider a smallish sort of crack in the
road (1 inch shift in height) and pssssssss. Could'nt believe it. I
realize at 190 lbs and riding tubular 19mm tires is potentially hazardous,
however, I raced on Wolber Record Route SP-1's (also 19 mm) for several
years before the first flat.
The Softride that I had the flat on is setup for racing, although I hope
to also put in some long training rides.
