I have stripped 2 frames. One a specialized and the other a CAADX. I used Klean Strip Aircraft Stripper. The CAADX frame was a bit more stubborn than the Specialized, but they both came out fine. It took about an hour with the paint stripper. Get a few pairs of nitrile gloves and a few plastic putty knife / scrapers. The worst part is goijng to be cleaning out the welds if the stripper doesn't penetrate into the grooves. Sanding will take as long as you want, dependent on the gloss you are looking to accomplish.
