RAFrame StiffnessComfort
Does a Lower RA Automatically Make a Racquet More Arm-Friendly?
Frame stiffness matters, but the string bed, weight, and contact point combine to create the impact you actually feel.
Player overview
Lower stiffness indicates a tendency for the frame to flex more, but the measurement method and location are limited and do not predict the overall comfort of a fully strung racquet.
Measurement guide
- Use RA as only 1 filter for narrowing candidates.
- With the same soft string, playtest contact near the center and near the frame.
- Record grip pressure, swing timing, and discomfort after the session as well.
Latest measurement
Comfort is the sum of frame, strings, technique, and load—not a single RA entry on a spec sheet.
