Columbia Commuter mopeds and their alias names had two different frames, stamped sheet metal, or mono-tube, and two different engines, Sachs 505 or Solo 255. All Columbia models had front and rear hand brakes, with 1970’s Magura controls. The early 1977-78 sheet metal frame models with Sachs 505 engine, had single-ended (universal) brake cable wires, with Grimeca type pinch bolts on the lower end. But the tube frame models with Solo engine and the late 1979-on sheet frame models with Sachs engine had American made brakes that took special brake cable ends, shaped like an “S”.
For Columbia cables, there are three model-categories:

Solo engine Columbia: On Colombia with Solo engine, the throttle cable carburetor end passes through the a M6-0.75 thread adjuster on the top of the carburetor. So the adjuster is not part of the cable, unlike Puch, and like on the Colombia with Sachs engine.
Sachs engine Columbia: On Columbia with Sachs engine, the throttle cable carburetor end passes through a M6-0.75 thread adjuster on the Bing carb elbow, so the adjuster is not trapped on the cable, and is sold separately. The carb elbow, aka curved pipe, can be either short or long. So there are two different throttle cables, short or long. The difference is 1/2 inch of exposed inner wire.
This exposed length of 4.5 inches is for a “short” elbow. Removed, the short elbow total length is 2 inch with the adjuster, or 1 1/2″ without, measured with a curved wire through the middle.
There are some Colombia’s with “long” carb elbows. They need this cable with a 0.5″ longer exposed length. The long elbow, removed, has a total length of 2 1/2″ with the adjuster, or 2″ without.
See Hercules Sachs choke cable for info.
