Bottom Brackets

The bottom bracket is a crucial component of a bicycle that connects the crankset to the bike frame, allowing the crankset to rotate smoothly. There are several types of bottom brackets, and the appropriate one depends on factors such as the type of bike, the frame design, and the type of crankset.
