Short version:

Has anyone ever tried these: Jagwire Non-Crimp Cable Ends? If so, any pros/cons?

Long version:

Next season we won't be allowed to race SSCX on multi-speed bikes with shifters disabled, so I need to be able to quickly (between races so under 15 minutes) convert my CX bike from geared to true SS (getting a dedicated SSCX bike is simply not practical at this time).

I'll be set up for 1x10, so it's pretty simple -- remove chain, replace rear wheel with one set up with a single cog and spacers, remove RD and install tensioner, install SS chain. Plan is to just zip tie the RD cable to the chainstay so it stays out of the way, but I can't get the cable through the RD adjuster barrel with a crimp-on cable end, and I'm worried that running with the end unprotected will cause it to get frayed in no time. I've had no luck soldering or super-gluing cable ends (the low-friction coating on the cables seems to interfere), so I'm looking for alternatives. The Jagwire non-crimp ends linked above look promising, but I'm open to other suggestions.

Posting here instead of the CX forum because though my problem is CX specific, the solution (cable ends) seems like a generic bike mechanics thing.
