As the days get longer and the weather warms up, it’s almost summer, prime time to dust off your bike and get it ready for the season. Before heading out, it’s worth taking a closer look at one of the most important systems on your bike: the gearing. Understanding how gearing works, and how it connects to your sprockets, can make every ride smoother, more efficient, and far more enjoyable. It also offers a useful window into the same precision engineering principles used in industrial applications, such as those developed by SDP/SI.
