Uncle Stretch said:Cool idea. You know just a suggestion , but I have found stretching built frames is a lot easier to use some thick 1'' pipe and weld it to the
BB instead of trying to lengthen those two tubes. Its stronger, and easier to make a good connection in front of the tire on the chain stays.
Maybe run them along the side of the single tube and then a flat plate on top and bottom. Makes for a really strong transition. It gives you
a lot of weld area.
