Product Description Carefully manufactured, highly precise: the 6801 bearings by Enduro Bearings You can choose between ABEC 3 steel bearings (type 1) and MAX bearings (type 2). ABEC 3 bearings from Enduro Bearings feature 10th-degree chrome steel balls that are twice as round as the industry standard, and manufactured to the highest standard. The treads are made of a 52100 carbon chrome steel alloy that is vacuum-generated and then hardened for extra strength and durability. A high-gloss polish ensures precision and low noise. MAX bearings are characterised by a 35 to 40 % higher load capacity than standard radial bearings. For 20 years Enduro Bearings has been manufacturing them specifically for use on mountain bike shocks. As its name indicates, MAX bearings are fitted with the maximum possible number of balls. The grooves in the races are deeper to accommodate the multiple lateral turning forces at the MTB rear pivot.
