The Blackbearing Ball Cage 1/4-7 is a high-quality replacement bearing retainer specifically designed for bicycle components, most commonly found in bottom brackets and rear hubs. Manufactured by the French brand Blackbearing, this component is engineered to provide a smooth, low-friction rotation for cycling enthusiasts and professional mechanics alike.

• Precision Spacing: The cage design ensures that the 7 balls are kept at equal distances, preventing clumping and ensuring uniform load distribution across the bearing race.

• Low Friction Performance: Optimized for a smooth and precise ride, reducing energy loss and mechanical wear.

• Standard Compatibility: This size is a standard "industry-fit" for many traditional square-taper bottom brackets and some larger front/rear wheel hubs.

• Corrosion Resistance: Usually finished with a protective coating to withstand the harsh environments of road and trail cycling.
