I need some help from the frame builders out there. I have a custom steel frame and would like to know if it is possible to replace the chain and seat stays on this bike. The intent is to 1) increase wheelbase, 2) increase tire clearance, and 3) install disc tabs.
I have purposefully not gone into the reasons for this request to stay focused on the primary question and not write an essay on the background. If some more details are needed I can elaborate.
