Enduro's Zero Bearing Jockey wheels are the ultimate drivetrain upgrade for riders seeking maximum efficiency and weight reductions. Zero Cermamic bearings use grade 3 ceramic (Silicon Nitride - Si3n4) balls which have tolerances are more than 2 times tighter than a standard ABEC 3 bearing. This is high level of tolerance combined with the high precision Delrin jockey wheels is critical in iradicating float and bearing play ensuring an efficient and precise drivetrain.
