Frequency Matching

Frequency matching is the process of building a set of clubs so that each shaft has a consistent stiffness progression, measured in cycles per minute (CPM).

Instead of relying only on the manufacturer’s stated shaft flex, the builder measures how much each shaft vibrates when oscillated. Clubs are then adjusted so the shafts follow a smooth, predictable increase in stiffness from the longest club to the shortest.

Fitters and builders use frequency matching to improve consistency across the set. When every club loads and unloads in a similar way, the golfer gets more uniform feel, timing, and ball flight. It helps remove unexpected variances that can happen in stock shafts, even within the same flex rating.

A properly frequency-matched set makes it easier for the golfer to maintain rhythm and trust each club’s performance.
