There is no commonality between cabling for these things. What you see on one computer will not be seen on another. After splicing at least 8 different cycle computers I have never yet encountered coaxial wire. They often look round like coaxial but really have two side by side conductors. I am sorry you had such trouble, but I have never had the least trouble splicing these things. I seriously doubt anyone who has soldered or spliced before will have any issues with the procedure.
Indeed, I have no idea why anyone would spec coaxial cable for cycle computers. The pickups are the simplest thing in the world - a magnetic reed switch.

No magic here. Any wire that completes the circuit will suffice. I used household, two conductor zip cord on my trike so it would be a heavy, permanent installation on a cycle I expect to own for 30 years. Of course the computer will give out before then, and no replacements will be available...one can dream.
I like the Planet Bike computers. They have nice heavy wire that is less fragile, the mounts are sturdier. They contribute to cycling every time you buy from them. Their prices are reasonable.
I know a lot of folks are put off by soldering, and who wants to buy and iron just for this. You can just twist the wires together and tape. That will work for a long time, but is ultimately going to get some resistance in the joints and stop being dependable. For the average cyclist who rides less that 50 miles a week only in the warm seasons this could be a very long time. If you are a higher mileage cyclist and ride in bad weather, then solder is better so the electrical connection never becomes an issue.

The wire is coaxial (small wire inside a conductive outer shield) and is so fine that I found it impossible to work with. I can solder, and have built numerous electronic kits up to and including a 25" color TV kit (in a former, much younger life). My 63-year-old eyes are just not up to such fine work these days. (Perhaps I should buy one of those expensive, fancy huge illuminated magnifiers for a work station?)
