MYSTERY

Mountain bike sitting in the garage, went to load it into the van for a trip, totally flat front tire. Took another bike. Pumped the mtn bike up, came back 4 days later, fully pumped, hasn't lost any air since - it has been a week. **********? I have ridden it with no problem. Schrader valve.
