For years I've thought about building a lightweight with a SA three speed. I like three speeds, but I don't like the clunky frames that are usually equipped with them. I finally got around to building the bike after I stumbled onto a '59 Carlton with a Reynolds 531 frame. I didn't get a fork with it, so I used one from a Raleigh Competition. I had the wheels built on my hubs by a local shop for $168. The rims are Sun CR-18 and the spokes are DT Competition. The front hub is an old Lambert with Japanese cartridge bearings and is incredibly smooth. I haven't calculated what I spent on the bike, but whatever the amount it was worth it to me. It's a wonderful ride!

Some of the shots were taken when I first built the bike as a single speed on fat tubulars. It was fun and very light, but it just wasn't practical for me.
