Grandson loves to ride my Litespeed Firenze when he visits and he got a too good price on one he could not pass up. Rear wheel tracking was just off the NDS stay, 4mm off center measured at the stay bridge. Read some pro and con posts here and as I have done steel cold setting and I could secure both stays I gave it a go using my home made hanger straightening tool as a gauge and bending tool. Two photos and today's ride confirmed it is good. Don't think it much more difficult that steel, would not hesitate to do a hanger however can imagine opening up an older frame to 130 would be an adventure without a frame table.
