Using the Shimano 105 RD - R7100 rear derailleur is easy. First, make sure it's properly installed on your bike according to the mounting type (10x1 Standard and Shimano Rear Direct Mount). It's designed to work with Shimano Road shifters, so just shift as you normally would to enjoy smooth and stable gear changes. When riding on rough terrain, the low - profile design will keep it from hitting the chainstay. For maintenance, regularly clean the derailleur to remove dirt and debris. You can use a soft brush and some mild cleaning solution. Check the chain regularly and make sure it's a compatible HG 12 - speed chain. If you notice any issues with shifting, it might be a good idea to adjust the derailleur's position or check the tension. Also, keep an eye on the sprockets and replace them if they show signs of excessive wear. Remember, a well - maintained derailleur will give you a better riding experience.
