Bottom Bracket
The bottom bracket is a crucial component of a bicycle that connects the bike's frame to the crankset, allowing the pedals to rotate smoothly. It houses bearings that enable the crank arms to turn freely while supporting the rider's weight and the forces generated during pedaling.
There are different types of bottom brackets, including threaded and press-fit designs, each with its own installation method and compatibility with various bike frames. Proper maintenance of the bottom bracket is essential for optimal performance and longevity, as it can affect the overall efficiency of the bike's drivetrain.
