I've purchase a frame of a 3 speed model of the OCC Schwiin Stingray and am looking to build it up into something fun to ride. I'm thinking about using a Sturmey Archer internally geared hub. My biggest question is can I extend the lenghth of the axle to make sure it fits into the amazingly wide rear forks. I have a stock wider bottom bracket that will made the chainline work but I think regular hub axles are too narrow to work. I was thinking about getting a nipple and short pice of axle welded on to the end of the hub Does anyone have any thoughts on this plan or better suggestions?
