What is a Bottom Bracket Cup?

A bottom bracket cup is an essential component of a bicycle, located at the bottom of the frame and connecting the chainset to the bicycle frame. It is responsible for allowing the crankset to rotate freely and is usually made of metal.

The bottom bracket cup is located inside the bottom bracket shell, which is the part of the bicycle frame that houses the bottom bracket. It is held in place by the bottom bracket shell, which is secured to the frame with screws.

The bottom bracket cup is important for the smooth operation of the bicycle, as it allows the crankset to rotate freely without binding. Without a bottom bracket cup, the crankset would not be able to rotate, and the bicycle would be unable to move.

Bottom bracket cups come in various sizes and materials, depending on the type of bike and the intended use. The most common size is the 68mm bottom bracket cup, which is used on most road and mountain bikes. It is also important to note that the bottom bracket cup must be compatible with the crankset and bottom bracket shell.

The bottom bracket cup is an essential component of any bicycle and is necessary for the smooth operation of the bike. It is important to ensure that the bottom bracket cup is the correct size and compatible with the crankset and bottom bracket shell.
