I have an older Schwinn touring frame that I like the ride and responsiveness of very much. It has Columbus Tenax tubing. I would like to buy or have built a titanium frame that feels the same but would have capability for wider tires and disc brakes.
How should I approach this? What would happen if the basic dimensions were recreated? How would titanium tube size be determined?
I realize that one answer is let the framebuilder decide but I would like to know more about the process ahead of time.
Thank you
