What is the difference between the threaded bottom bracket and the press-fit bottom bracket of the MTB Bottom Bracket?

There are significant differences between the threaded bottom bracket and the press-fit bottom bracket of the MTB Bottom Bracket in many aspects. Here’s a detailed comparison of these two bottom bracket types:
First of all, from the perspective of installation method, the threaded bottom bottom bracket is installed by threading the bottom bracket into the base of the frame, which usually requires the use of special threaded components. This method of installation is relatively straightforward, but requires ensuring precise alignment and retention of the threaded sections. The press-fit bottom bottom bracket uses special tools, such as pressing blocks, to press the bottom bracket into the base of the frame. This method of mounting does not require threaded parts, but does require the use of special tools to ensure a secure installation.
Secondly, from the perspective of the disassembly method, the disassembly of the threaded bottom bottom bracket is relatively simple. You only need to use an appropriate tool to apply reverse force to remove the bottom bracket. Removal of a press-fit bottom bottom bracket is relatively difficult, requires the use of special tools, and may require more time and effort.
Furthermore, from the perspective of service life, threaded bottom bottom brackets usually have a longer service life due to their screw connection method. When the screw is tightened, the connection becomes more stable and less prone to wear. Press-fit bottom bottom brackets may require more frequent inspections and maintenance to ensure they are securely installed and prevent loosening, thereby ensuring riding safety.
In addition, press-fit bottom bottom brackets are generally lighter in terms of weight and appearance, which helps reduce the weight of the entire vehicle and improve riding efficiency. At the same time, its simple design is also favored by many cyclists. Although the threaded bottom bottom bracket is slightly heavier, its solid structure and stable performance have also won widespread praise.
In general, threaded bottom brackets and press-fit bottom brackets each have their own characteristics and advantages. The threaded bottom bracket is relatively easy to install and disassemble, has a long service life, but is slightly heavier; while the press-in bottom bracket requires tool assistance to install and disassemble, but is lighter and has a simpler appearance. Cyclists can choose the appropriate bottom bracket type based on their needs and preferences. Whether you're looking for performance or portability, you'll find a suitable choice in both types.
