Enduro Angular Contact bearings engage all of the bearing's balls to spread the force over a larger surface area, minimizing wear and increasing bearing life. This is particularly important in applications like BBs, where there are constantly changing lateral loads on the bearings, which is typically the primary cause for premature bottom bracket bearing failure. 440C stainless steel bearings offer high corrosion resistance for adverse riding conditions This high-grade stainless steel is perfect for rolling elements due to its high-carbon content and is harder than other stainless steel variants Bearing races are made of 440C stainless
