The frame to be considered for cold setting is the original IRO group buy frame. I would like to use an alfine 8 speed hub with it but cannot buy a new frame with the appropriate spacing. Using the Sheldon "Riding into the Sunset" Brown method, is it safe to cold set this frame 7.5 mm on each side? I only weigh 120 lbs. I plan to check the alignment as I go and verify dropouts aligned properly. I'm more or less asking if anyone has done it successfully and if there's a chance of it working.
