Bottom Brackets

Choosing the right bottom bracket is one of the most important decisions when building or upgrading a bike because it directly affects performance, durability, efficiency, and long-term reliability. The bottom bracket connects the crankset to the frame and allows the cranks to rotate smoothly, so selecting the correct type ensures optimal power transfer with minimal friction.
