What is a square taper bottom bracket and how does it differ from other bottom bracket types?
A square taper bottom bracket is a type of bicycle component that connects the crankset to the bicycle frame. It consists of a spindle with a square-shaped taper on one end, which fits into the corresponding square hole in the crank arms. The other end of the spindle is threaded to allow it to be installed into the bottom bracket shell of the bicycle frame.
The main difference between a square taper bottom bracket and other bottom bracket types is the way the crank arms attach to the spindle. In square taper bottom brackets, the crank arms slide onto the square taper and are secured with bolts or nuts. This design has been widely used for many years and is known for its simplicity and durability.
In contrast, other bottom bracket types, such as external bearing or press-fit bottom brackets, use different methods to attach the crank arms. These designs often incorporate external bearings or press-fit cups, which can provide improved stiffness and efficiency but may require more maintenance and specific tools for installation and removal.
Overall, the choice of bottom bracket type depends on various factors, including the bicycle frame design, intended use, and personal preference. It is important to consider compatibility with the crankset and frame, as well as the advantages and disadvantages of each type when selecting a bottom bracket.
