Haven’t used the Singleator. I did have a Rennen tensioner that was sweet but I don’t think it would work with modern dropout/axle systems.
I did this [Zee hack](https://m.pinkbike.com/forum/listcomments/?threadid=169604&pagenum=11) and it was sweet on the hardtail but couldn’t wrap around a big enough cog for my FS bike.
Generally, other than my FS experiments, I’ve had bikes with adjustable drops other than my Gary Fisher which had okay chain tension with a 32:20 magic gear.
