I’ve always been a big Columbus fan. The first frame I ever built was Columbus Genius, a very thin and for it’s time sophisticated tube-set. It was the last tube-set a newb should be building with but I didn’t let that slow me down. Columbus has always been an innovator in alloy, tube wall manipulation and tube shape. I don’t know that any other tube company produces the beautiful shapes that Columbus does. To this day almost every bike I build has some Columbus in it. Below is a cool article about Antonio Columbus and his life in the cycling business. I thought you might find it interesting.
