BLACKBEARING BALL CAGE BEARING | 5/32-22 (33 X 39.5 X 3.97)
The Blackbearing Ball Cage 5/32-22 is a high-density bearing retainer specifically engineered for oversized 1-1/8" and 1.5" bicycle headsets. Featuring a 22-ball configuration, this cage provides maximum support and stability for the front end of modern mountain bikes and performance road bikes, ensuring smooth steering even under heavy trail or road vibration.
Features
-
Maximum Ball Density: With 22 balls, this is one of the highest-density 5/32" cages available. This extra ball count significantly increases the load-bearing surface area, preventing the common "indexed" (notchy) steering feeling caused by bearing balls digging into the headset cups.
-
Oversize Compatibility: Specifically designed to fit the larger races found in 1-1/8 inch and some 1.5 inch "tapered" or "oversized" headset systems common on modern MTB and Road frames.
-
Service Efficiency: The cage keeps all 22 balls in a perfect circular alignment, allowing for quick "drop-in" installation during a headset overhaul without the risk of losing individual balls.
-
Engineered Precision: Manufactured by Blackbearing to ensure minimal friction and consistent rotational performance, meeting the high demands of competitive cycling.
