This Is…Holy Crap This Is Amazing
Written by Boston Biker on Apr 09This has got to be the craziest, most elegant solution I have ever seen to this problem.
This weekend I finally solved a particularly tough chain tension problem that I’ve been having on my winter commuter/guest bike with the addition of a “ghostring” or “ghost ring” or “ghost chainring” (I’m unsure of what the proper name for it is, if there is one). The idea is simple, but when first presented with it any well-seasoned cyclist will surely look askance at the contraption. I’m here to say: so far, so good!
GHOST RING!

I’ve seen this tweak used on tandem timing chains before. And the Renold chain company has sold a line of flexible rings for many years that are intended to take up slack in a chain transmission assembly just like this.
