My new bike had its 4th flat in 6 weeks. This time a short fat screw punctured the Forte ST/K tires (the previous flats were a different tire). The screw head was pretty big so I assumed it punctured the tube and was the only thing holding the air in. It was flat by the time I left work. Maybe if I pulled it right away instead of riding on it, it might not have hit the tube? Would be late for work if wrong.
The good news is I bought the Crank Bros Speed Tire Lever last week and it works GREAT. I used to fight the tires for maybe 20 minutes trying to mount them by hand but this thing had it on in less than a minute. Pretty light too.
