Ball bearings should always be your first upgrade as they reduce friction and rolling resistance, which means higher speeds and longer run times. Ball bearings require almost no maintenance and last much longer than stock plain bearings. Yeah Racing Ball bearings have very low rolling resistance. They are made of high quality steel. They are pre-lubricated to ensure smooth operation.
The use of rubber dusters provides increased protection against the ingress of dirt during operation, while metal dusters, on the other hand, offer even more reduced friction.
