This is my 62 years old Koethke racing bike. It has been built for my father in 1952 at the Cologne based manufacturer. Koethke doesn’t no more exist since 1992. Today only the frame and the fork is original. Other parts have been changed over the years. Since two years I’m working on this bike, but sometimes it’s hard to get the right parts.
Tho most complicated parts have been the brakes because of the lon measure from frame to wheel (5.9 cm). Now a pair of Trekk brakes are mounted. The next parts have to be the gear parts. Now I have a Shimano “Alvio” ;-) but it works fine while I’m using this bike still as a training bike. I’m looking for a Campangnolo-Set, but I need a 5 gear cassette in the back.
