I noticed over the last few weeks that I had a slow leak on my front tire and I had to keep pumping it up about once a week. I decided to change out the front tube today.
I suspected that the valve was leaking since it was very slow. I did not think I would be able to find the leak since it was so slow but I was wrong. There was an easily identifiable leak. It was about 5 1/2 inched from the valve on a seam. The leak was on the side facing the rim not the outer tread. I did not see any foreign material that could have caused the leak. The seam is probably just the weak point and will fail first. I can't complain-- this is the original tube having 2808 miles of service and almost 2 years.
The tube was a Kenda 28-U-021. There was a stamp "13", perhaps the inspector and a number 1115650806 stamped on it. I replaced it with a tube I got from PricePoint.
