Today I have a problem with my bike. The back tire was losing air. I changed it just before I was departing for work, but the tire continued losing air. I don’t know why, I guess, maybe I made a mistake when I installed it. So, as I was in a hurry, I decide to go to work with the tire without air, It was a little uncomfortable, and I was a little concern that I could damage my bike in this way. But I got to job, and then when I have to come back, in the night, I pass to inflate the tire to a gas station, and I could got home, over my bike, with the tire full. I guess it must have had a tiny hollow in the rubber of the tire, so that was why It was losing air, but still I could get home very quickly.
Actually, it was a very nice trip, compared to the trip of the morning (with the tire without air)
