Identifying Brand
 

Hi, i am from Turkey.
I need some help. I have a bike which belong to my father, i like to restorate it. But i have no a brand name for searching clue, only there is characteristic sign "S" on the frame where the rear brake is mounted (You can see in the picture). Also there are "Weinmann" brake set; shifters and derailleurs are "Sachs". It could be a european bike, the time period is 1970's. Could you help find the bike's brand name?

Please show more details of the frame, although that is a VERY distinctive rear brake bridge! The width and threading of the BB can help pinpoint country of origin.

Hi,
Tonight i have met a suprise on my bike... I see that my frame is made by TANGE in Japan. I search little about Tange that is a specialist on his branch, so it makes me happy and proud. I have a thought of my bike could be bad replication of some small manufacturer. However, the frame is Japan but all mechanisms on it, are made of Germany, so it should mean that the frame was only exported from Japan to Germany. Then mounted other components for sale in Germany, but under which brand name? Should it begin with letter 'S' ?

Tange was a maker of tubing that was used by many different bike companies. So the bike could still be a German bike made with Japanese tubing.

Hello Pompiere,
I contacted to Tange, said as you... They made tubes, not frames.

Also I noticed a frame number on frame under the bottom bracket. It is 77192213.
Does it help me in any way? Do the bike manufacturers use different chassy number from each other as automotives? Does the number point a manufacturer?

Best regards,
