    BMX Bottom Brackets
    BMX race bottom brackets house the bearings that let your cranks spin smoothly, making them a key part of your drivetrain performance. A high-quality bottom bracket minimises friction, maximises power transfer, and delivers a crisp, responsive pedalling feel. It also has to be strong enough to handle the explosive forces of sprints, jumps, and landings. Poor-quality or worn bottom brackets can cause play in the cranks, loss of efficiency, or mechanical failure. In BMX racing, a smooth, durable bottom bracket is essential for turning every pedal stroke into maximum speed.
