BK-5057 - 1/8 (0.125) Grade 5 Steel Balls - 50 Pieces

Enduro offers high-quality loose ball bearings essential for maintenance and repair of your bicycle. These Grade 5 steel balls meet or surpass a 5/1,000,000 sphericity tolerance, ensuring extremely precise and round balls—so much so that most steel races cannot be ground to match this level of accuracy. These balls are identical to those used in Enduro ABEC-5 bearings, guaranteeing reliable performance. While a few years ago, Grade 25 balls were considered top-tier, used only in premium hubs and bottom brackets, today, Enduro's entry-level ABEC-3 bearings feature Grade 10 balls, with Grade 5 balls offering a higher level of performance and durability for demanding cycling applications.
