Doesn't seem rougher than normal chains

Maybe slightly as the chain is slung under the tire so it's travelling faster than it would otherwise just being mounted onto the tire?

The chain gets compressed between the tire and the ground. It can’t really have a much different speed than the tire itself.

I was thinking about the initial swing in.
