The Blackbearing Ball Cage 3/16-15 is a high-precision bearing retainer designed primarily for 1-inch bicycle headsets and high-density BMX hubs. With a 15-ball configuration, this cage provides a significant upgrade in stability and steering smoothness compared to standard 7 or 9-ball retainers.

• Enhanced Load Distribution: The 15-ball count allows for a much higher density of contact points. This is critical for headsets, as it distributes the weight of the rider and the impact of the road more evenly across the races, preventing "indexed" or notched steering.

• Low Profile Design: At only 5mm thick, this cage is designed to fit into the narrow profiles of classic 1" threaded and threadless headsets, providing a compact yet robust bearing solution.

• Precision Steering: Specifically engineered to eliminate play and friction in the fork-to-frame interface, ensuring responsive and smooth handling.

• Workshop Ready: Frequently available in packs of 10, these are a staple for bicycle restoration projects and professional service centers.
