I started out fairly early on my Seven Axiom for a relaxing solo road bike ride. It was a cool beginning as usual, but gradually warmed up to be very pleasant and sunny. While on Valencia, I stopped to watch the radio-controlled planes do their acrobatics and took a few pictures, but they are hard to capture while flying. As I was beginning to anticipate a morning finish to a 32-mile ride, I heard the hiss of my back tire going flat. The same tire had just been changed yesterday! As I began to work on fixing it, a nice couple stopped by offering to help. Of course he changed the tube much quicker than I am able to. As they continued on their ride, I was about to do the same, when the same tire flattened again!! So I again removed the back tire; just then a team of young cyclists on their trainig run came by. They quickly fixed the situation for me. I was cautiously biking on the Pantano Bikeway just about to turn onto Stella, when AGAIN I heard the hiss of the tire losing air! So I had 3 flattened tubes and no more turn to. At that point I knew there were than just miniscule punctures involved. I called my wonderful neighbors asking for a ride home and began walking until they met me to pick me up. What I discovered after I got home & began inspecting the rim is that the liner had worn through at the point a spoke attaches and was tearing the tube. So much for my solo ride, but I did get to talk to a number of nice helpful people today. I found an open bike shop (many are closed on Sundays) and got the problem fixed in 20 minutes so I am ready to go again!!
