I am once again cycling after 28 years and there has been many changes in technology, therefore I am joining this forum to learn about these changes and get opinions. I do all the building/rebuilding of my bikes so the help I get from my fellow cyclers and mechs is needed and appreciated. About me: I've cycled most of my life erasing the past 28 years. I'm now into it bigtime. I used to ride road and race, but at 66 years of age, I'm going with MTV's and commuter. My favorite ride was spending $5.00 to take you to the San Juan islands. You could stay for a week and hop on a ferry to next island, and return home, all on that same $5.00.
