Loose ball bike parts are still out there, so Enduro carries the loose balls you need to complete the job.
Grade 25 balls meet or exceed 25/1,000,000" tolerance of sphericity and is considered extremely round. Only a few years ago, Grade 25 would be considered a very high grade ball, used only in the best hubs and bottom brackets. Today, Enduro's entry-level ABEC-3 bearings feature Grade 10 balls and then Grade 5 or grade 5 as you go up in price and performance.
