Yeah Racing (#YB6027Y) Yellow Teflone Ball Bearing (12x21x5mm)
Ball bearings should always be your first upgrades; that reduce
friction for less rolling resistance, and that means higher speed and
longer the running times. Ball bearings hardly require maintenance
and last a lot longer than stock Oilite bushings.
Our Yeah Racing Ball Bearings have the lowest resistance.
They are manufactured perciously by Aircraft quality stainless
steel. Pre-lubricated with light protection oil, not any grease to
ensure its excellent performance!
