What is a Bottom Bracket in Cycling?

The bottom bracket is a central component of a bicycle frame, located between the crankset and the headset. It is the part of the frame where the crank arms are attached to the frame and rotates around the axle. It is also known as the axle or spindle.

Bottom brackets play an important role in the performance of a bicycle. They provide the connection between the crankset and the frame, allowing the crankset to rotate freely while keeping the frame rigid. This is essential for efficient pedalling and a smooth ride.

There are three main types of bottom brackets, each with its own advantages and disadvantages. The three types are cartridge, square taper, and external bearing bottom brackets. The most popular type is the external bearing bottom bracket, which is lighter, stiffer, and more durable than the other two types.

According to a survey by the National Bicycle Dealers Association, the most popular bottom bracket type among cyclists is the external bearing bottom bracket. This type of bottom bracket is used in more than 90% of all bicycles sold in the U.S. and is the preferred choice of both amateur and professional cyclists.

The bottom bracket is an essential component of any bicycle and plays an important role in the performance of the bike. It is important to choose the right type of bottom bracket for your bike to ensure optimal performance and a smooth ride.
