What is a Bottom Bracket on a Mountain Bike: Everything You Need to Know
The bottom bracket on a mountain bike is the component that connects the crankset to the bike frame. It consists of two bearings that allow the cranks to rotate smoothly and transfer power from the pedals to the rear wheel. Bottom brackets come in different sizes and styles to fit different frames and cranksets, and can be threaded or press-fit into the frame. They require regular maintenance, such as cleaning and lubrication, to ensure optimal performance.
