Floating Chainring

I passed this bike the other day and something seemed odd.


I got closer and yes, this did seem odd at first.


But my feeble brain then kicked into gear and I realized that this “floating” chainring was a brilliant form of chain tensioner. Simple, a bit elegant in my mind – and yet there is that feeling of unease at having something solely held in place by tension. Reader reaction welcome in comments.
