Joseph Kuosac 118mm Bottom Bracket for Brompton Bicycle

Features & Benefits

Before founding Joseph Kuosac, Joe spent over 20 years designing and manufacturing automotive-grade and heavy-duty industrial products that meet the highest standards of quality and reliability.
He brings the same design philosophy and professional engineering practices into every Joseph Kuosac product.

The Joseph Kuosac Bottom Bracket is engineered with drivetrain dynamics in mind. It is specifically designed to handle the uneven and alternating forces generated by pedaling between the left and right legs.
Joe views the rider’s feet and cranks as the equivalent of an automobile engine’s crankshaft — demanding strength, precision, and long-term durability.
