Enduro Bearings BB Kit BB90 95 Shimano Hollowtech II (24x37mm) - ABEC 3

ABEC 3: A standard value used to measure the tolerance of the surface of the rolling bearings. There are five classes: 1, 3, 5, 7 and 9. The higher the ABEC class, the greater the precision, efficiency and speed capacity, but the highest ABEC classes are not necessarily the fastest rotating parts. All quality manufacturers worldwide use at least ABEC 1 as standard. At Enduro, the minimum standard is ABEC 3. ABEC 3: Steel balls Grade 10. Race in a 52100 chrome alloy and high-carbon steel. ABEC 3 standard. Depending on their application, these bearings use LLU or LLB seals; even when marked with 2RS.
