BK-5039 - 1/8" (0.125") Grade 10 Steel Balls - 100 pieces
Loose ball bike parts are still out there, so Enduro carries the loose balls you need to complete the job.
Grade 10 balls meet or exceed 10/1,000,000" tolerance of sphericity and is considered extremely round. Only a few years ago, Grade 10 would be considered a super premium grade ball, used only in the best hubs and bottom brackets. Today, Enduro's entry-level ABEC-3 bearings feature these same Grade 10 balls, with Grade 5 balls used in our higher performance bearings.
