HOW TO Mensurate A Restriction DISC


Take the approximate work out of the equation by following this short tutorial on how to measure your restriction disc rotor

Please note: All measurements are in mm

1. ID = Within Bore: Measure from within border to within border.

2. OD = Exterior Diameter: Measure from exterior edge to exterior border.

iii. Measurement from inside border of mounting hole to inside edge of bolt pigsty.

4. Bolt pigsty diameter: measure out from inside edge of bolt pigsty to opposite inside edge.

5. PCD = Pitch Circle Diameter: To measure out this, use the following equation;

ID + (2 10 Measurement 3) + Measurement 4
Eg: 90 + ( 2 x 1.5 ) + 17 = 110mm

half dozen. Thickness: Measure disc thickness past either continuing disc vertically or lay on a apartment surface.


7. Offset: Identify your disc on a flat surface and measure from the surface to the pinnacle of the disc (including the disc thickness)


8. Types of commodities holes
