Core Block™ - 60mm
Ronstan's Universal Bearing, incorporating their proven 2-stage bearing system, provides dynamic and high static load performance:
Stage 1 - Under moderate loads, Acetal ball bearings ensure minimum friction.
Stage 2 - Under heavy loads, where deformation of ball bearings alone would result in increased friction, a sliding Acetal bearing on a polished stainless steel race takes over, maintaining low friction performance.
Universal head with full 3-axis articulation. Head posts can be locked at 0° or 90° by using a 2.5mm Hex/Allen Key. Block RF64110 features a removable becket pin for fitting of pre-spliced lines.
