Over 70 now but biking more than ever. Mainly doing tandem rides on rail trails. Dont like depending on bike shops that require me to haul my bike into town and park in a parking garage. They all tend to cater to the college kids which is their bread and butter. Some of my bikes are older than most college kids. The newest is our tandem and it is now over ten years old. Fixing it generally requires finding new compatible parts which can be tough. That is why I am joining this forum.
