The disassembly process of the bottom bracket during bicycle maintenance

The bottom bracket of a bicycle is also considered a consumable or wear product. Riding for a period of time or distance requires maintenance or replacement. There are also many types of bottom brackets. From the specific shape of the bottom bracket, it can be basically divided into several types such as ball-bearing bottom brackets, integrated bottom brackets, and through bottom brackets. At present, the center shaft of the bead block is basically eliminated, and the integral shaft and the center shaft are used the most

Generally, the one-piece bottom bracket is recommended to be maintained once a year and needs to be replaced in three years. If abnormal noise occurs or the bearing is stuck during use, it needs to be replaced. Whether it is maintenance or replacement, disassembly is a process that requires effort.
