I haven't been biking for quite a while but just started back this year. I am 47 and rode a variety of geared bikes in California - even had a 3-speed for a while. I have a Trek 1100 which is being transformed into a SS although after reading Luis' post I am considering a Suicide Fixie. I have a set of Mavic Paris Gao Dakar hubs that I laced up back in 1990 or 1991 with DT double butted spokes and now I am sentimental and want to keep them. Our local machine shop has agreed to tig weld the horizontal dropouts in for me. I am working on polishing all the bits that I am going to keep and purchasing items for the project. I hope that I will have a bike I can knock around town on, ride with friends that are slow and have it look nice too.
I live at the top of a hill and our town is built on the edge of a small mountain. I'll probably go with 60" or less for the gearing so I don't have to push it home or more likely ride it home and hurt myself in the process.
Anyhow, I am glad to find this thread and have enjoyed reading through the posts.
