I recently replaced my front tire. About 3 days post replacement I noticed that the pressure in that tire was at about 50psi (Its a road bike - I keep it around 120). I pumped it up and hoped for the best for my ride home.
I didn't have time to check for the leak that day so I left until the next day. Next day the pressure was fine.
about 5 days later it again dropped down to around 50 and I pumped it up.
Now its been about 2 weeks and the pressure is holding as well as it usually does.
Whats going on here?
