Loose ball bike components are still in circulation, and Enduro stocks the loose balls necessary to complete your project.

Grade 5 balls surpass the 5/1,000,000" tolerance of sphericity and are renowned for their exceptional roundness, to the extent that races cannot be ground to match that level of precision. These balls are equivalent to those found in Enduro ABEC-5 bearings. Just a few years ago, Grade 25 would have been considered a premium-grade ball, reserved solely for the finest hubs and bottom brackets. However, today, Enduro's entry-level ABEC-3 bearings come equipped with Grade 10 balls, with Grade 5 or Grade 3 options available as you progress in both price and performance.
