When I ran a shop in the early 80's I had just assembled a nice (very nice) new Trek road bike with Specialized Turbo S clenchers rated at 110 psi.
Fully inflated the tires, rode it around the block. (Sweet!) and placed it on proud display in the front window.....in the hot sun.
About an hour later...
BLAMO!!! Tire failed and blew the bike right out of the display box and onto the floor.
Scared the living S*** out of me and I dove under the work bench with my ears ringing. The real funny thing was my co-worker who was a Viet Nam vet. He came rolling out of the back office with Colt 1911-A1 in hand ready to rock and roll.
I always felt safe working late doing bike assembly when Ol' Vince was around.
