This 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 Iâ€™ve been having on my winter commuter/guest bike with the addition of a â€œghostringâ€ or â€œghost ringâ€ or â€œghost chainringâ€ (Iâ€™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. Iâ€™m here to say: so far, so good!
If you find it takes too long to get to your office by bike, you wonâ€™t solve the problem with a car. The problem is not that biking is too slow. Itâ€™s that you live too far from work! Keep biking to remind yourself of this, and the problem will solve itself, either through fitness or switching houses or jobs.
From here, more good stuff near the end.
