If the pivot on your Shimano 105 derailleur is bad, it will need to be replaced. Depending on the type of derailleur, you may be able to replace the pivot yourself, or you may need to take it to a bike shop for repair. If you can replace the pivot yourself, you will need to purchase a new pivot from a bike shop or online retailer. Once you have the new pivot, you will need to remove the old one and install a new one.

My passion for bikes started when my parents opened a shop in the 1980s called Parker Bikes (we were located in Parker, Colorado). My love for cycling has continued since then, in my work and with my hobbies of road cycling and mountain biking. After my parents’ shop closed, I worked for other bike shops (including Lee’s Cyclery in Fort Collins), where I built and sold bikes, fixed and tuned up bikes, and managed inventory.
I love working on bikes and want to share my passion for cycling with others. So, next time you’re talking cycling with someone and wondering how to get started or where to go from here, you can think, “I know a guy!”
