Skipping or badly performing gears are a terrible thing to have, the game of gear roulette when you shift a lever and hope the chain goes onto the correct sprocket can be a frustrating thing. Lets solve those gearing problems!
In the setup we are looking at today, they are operated via a bowden cable. The cable starts in the shift lever and is held in place there via a small barrel shaped end that sits with the within a ratchet mechanism, it then finishes at the derailleur where it is clamped in place. So when you move a shift lever the cable, which is connected to the moves on a ratchet system that allows the cable to travel a pre-determined amount which then correspondingly moves the rear derailleur the same distance as the gap between adjacent cassette sprockets.
