Last night I was riding into a parking garage with a steep decline before the entrance. I hit the bottom of the ramp hard and lost most of the tire pressure in my front tire in a split second. I thought it was a pinch flat or blowout right away so I walked it over to a local bike shop where they had a air hose and was able to air up the tire which held the air and is still inflated to the proper pressure this morning. Does anyone know what may have caused the air loss and subsequent flat?
It is a road bike with racing tires and presta valves. I also check the pressure and fill the tires every couple of days so it wasn't flat already.
