Can these (?? biopace) rings be used on fixed wheel? I wonder what they are like to ride.
Chain's a bit slack, tight, slack, tight, slack.......
That was my initial thought
but thinking about it I can see that it is not necessarily the case. However, even if chain tension remained perfectly constant I suspect that at higher cadences the chain motion might predispose to chucking the chain off.
Still curious about how it feels to ride with these rings.
