1/4" Bicycle Rear Hub Bearing Balls, Fits Shimano Campagnolo, 100 Pack

1/4" Bicycle Rear Hub Bearing Balls, Fits Shimano Campagnolo, 100 Pack

• REBUILDS FIVE REAR HUBS WITH SPARES — Most rear hubs take 9 balls per side, or 18 per wheel, so this 100-count pack covers five complete overhauls plus a handful of extras for the ones that roll off the bench.
• PRECISION CHROME STEEL — Through-hardened AISI 52100 chrome alloy steel, precision ground and lapped to Grade 25 tolerance for consistent diameter, high sphericity, and a smooth, low-drag spin under load.
• CORRECT SIZE FOR MOST REAR HUBS — 1/4 inch (6.35 mm) is the standard ball size in cup-and-cone rear hubs across road, mountain, hybrid, BMX, cruiser, and vintage bicycles. Note that most front hubs use 3/16 inch instead.
• MORE THAN JUST HUBS — The same 1/4 inch size is used in many older three-piece bottom brackets, coaster brake hubs, and vintage pedal spindles, making these a versatile shop staple beyond wheel service.

• SHIPS LIGHTLY OILED — Balls arrive with a protective film to prevent surface rust in transit. Wipe clean and pack in fresh bearing grease before installation. Measure your old balls or check your service manual before ordering.
