PBR Staal C45 ultralicht achtertandwiel 4692 - 520 Aantal tanden:48 tanden Greatly limits particle infiltration

Greatly limits particle infiltration

Another advantage is the fact that the clamping screws do not influence each other and thus a more precise tightening torque can be achieved

Reduced top land

unlike Industrial 2RS type ball bearings offer low torque resistance and hence weak resistance to water intrusion
