I now it's an odd question, but I want to buy a long length - probably about 7 meters - of the sort of cable used for bicycle brakes, i.e. with a wire running inside an outer sheath.

The problem is I don't know what it's called, and if I try to enter "bicycle brake cable" all it shows is cut lengths for bikes.

Does anyone have any idea how I can search for it? Thanks for any suggestions!
