I'd noticed the reinforcing collars but the catalogue says "titanium or steel front". However, like you I'm pretty sure it's 6061.
The pivot in the catalogue photo is frustratingly fuzzy but it's definitely different to the Jakarta bike - maybe this is due to material selection i.e. aluminium not titanium?
There's only one person who has the answers but I don't think my grainy photos were compelling enough for Daryl to engage. Better luck next time... In the meantime all we can do is speculate.
1. Where was it made – USA or outsourced? Part outsourced and assembled in the US?
2.Maybe it was made in Indonesia and has always been there? That would be a big departure but these were the final days of Funk, so I guess anything was possible.
3. Did Funk pay for a license to use the AMP patent? It looks like a Horst link, so I'm guessing that they did?
Accumulates Speculation. Fantasy?
