Enduro BB30 Bearings ABEC 5 Kit - Enduro Steel , inc seals / spacers / clips

Upgrade you stock bottom bracket. Enduro bearings are designed to spin more efficiently and for longer. Using Enduro's ABEC 5 is the next performance step up from the popular ABEC 3 range. By using military level, high precision HRC-64 hardened Grade 5 Chromium Steel Balls, and 52100 High-Carbon Chromium-Alloy mirror polished races. This combination allows Enduro's ABEC 5 bearings to use tolerances twice as tight as ABEC 3, and operate without any noise. The Graphite/Nylon ball retainers allow virtually frictionless movement and provide constant lubrication to maximise the life of the bearing.
