Indexed MCS Measurement For Masts 
Related links: New masts, Used masts, Metric conversion table

The INDEXED MCS measurement system was developed to compare stiffness between masts of different lengths.

MCS numbers only mean a stiffer or softer mast when comparing masts of the same length. For example: compare the 430/25 and 460/25. Even though the 430 has the same MCS stiffness number (25), when a 30cm carbon base extension is added to reach the 460 length, the stiffness is actually softer than the 460/25. By indexing all masts to one length (465cm), it is possible to use the MCS concept and compare masts of different lengths.

Indexed MCS uses some arithmetic to relate every mast stiffness to 465cm length for more precise relative stiffness numbers.

INDEXED MCS = OVERALL LENGTH CUBED DIVIDED BY MID POINT DEFLECTION X 465 SQUARED

Example: Compare a 430cm with a mid-point deflection of 172 and a 460cm with a mid-point deflection of 184.
