Rat Bikes! Pub Bikes Beaters! Frankenbikes!

using it on a shitty conversion that already has a half link, waste of money, but of course it has its uses, but the real solution is just get a frame with track ends.

I'll assume you're talking about the bike in the video - but what would you expect from Road.cc... ;)

And, as I just said, the real solution is get whatever the hell you want to ride and make it work for you. Not limit yourself to track frames/geometry.
