How Form 2220 Adjustment 2023-2024

The most common question we get is, "How do I fix my shifting? Maybe it's not reaching all the gears or maybe it's making all sorts of noises." Whatever the issue, and regardless of the maker level, this video on mechanical rear derailleur adjustments will help you dial in your shifting for optimal ance. Hi, Calvin Jones here from Park Tool Company. We hope this video will give you a whole new outlook on your bike shifting. And before we begin, here is a quick overview of the components and procedures. The rear derailleur is the mechanism that shifts the chain at the rear cogs. The derailleur is connected to the shifter by a cable that passes through housing. Bikes commonly use an index shifter that moves two cables in small, predetermined increments with each click. Inside the derailleur body is a spring that constantly pulls the derailleur outward, and our cable is constantly holding against that spring in various shift positions. Derailleurs are fitted with limit screws that stop the derailleur from moving too far inward and too far outward. Here we can actually see the limit screws, stopping the linkage at each end. The function of limit screws is to prevent the chain from going into the spokes or into the frame. Our first procedure will be to set the H limit screw, and after that, we'll move on to indexing. Indexing is the process of lining up our guide pulley with the cogs so that each shift lines up with each cog. The barrel adjuster, located here or up at the shifter, allows us to move the shift increments, as shown. After indexing, we'll dial in our other limit screw. Then we'll check our B screw adjustment, and we'll explain more on that later. For now, describe...
