once again I am asking for help. Does anyone know what the frame is. is quite unusual:
1. pivot axis of the rear shock is centered.
2. rear wheel hooks: ritchey.
3. Two steel cables limiting the operating range of the rear shock absorber !!!.
4. the main frame tubes are externally pressed...
I think it is titanium because:
1. weight (steel of this length weigh more than 200 gr).
2. It is not ferromagnetic.
3. welds.
I don’t know what bike it was mounted on, but the color is characteristic (anodized gold). do you have any ideas?
