Introduction
The rear derailleur is a part of the bike used to shift the chain between the smallest and biggest chainring/sprockets on the rear crankset. The gear assembly on the bike allows you to switch between the highest and lowest gear combinations. The derailleur can get misaligned sometimes and it is important to know the steps to re-align it when this happens. This guide specifically focuses on the "Power Index System" brand of derailleurs.
