So last night, our local bike club had a tech talk about aluminum (fascinating stuff). One of the guys presenting is an engineer for an aerospace company and runs a aluminum fabricating workshop on the side. I chatted with him afterward and mentioned how I ride a Brammo, which is kind of an orphan bike at this point, and there may be some interest in custom parts or even replacement parts, since nobody is making them. So would there be any actual interest? Off the top of my hand, I would think that a chain adjustment replacement part would be neat, just because the current one is kind of janky. He said obviously much depends on the part and the size of the production run, etc... but he was intrigued and has contacts with other fabricators, etc..
