Nylon Gauge 16 1.34 mm In production

Lab measurements for Head FXP Power 16, ranked against all 789 strings in the database. Every figure below is a testing-machine result at a fixed reference tension, not a playtest opinion.

Measured values

Stiffness

194lb/in

lower = softer, kinder on the arm

Tension loss

26%

lower = stays where you strung it

Energy return

96%

higher = livelier, more free power

Spin potential

4.6

higher = more spin off the string bed

Ball bite

0.403COF

higher = grabs the ball harder

Snapback

0.087COF

lower = strings slide and snap back

More from Head

What these numbers mean

Stiffness · lb/in

How much the string bed resists deflection. Higher plays firmer and more controlled; lower plays softer and easier on the arm.

Tension loss · %

Share of the reference tension the string sheds under a fixed test protocol. Lower means the bed stays where you strung it for longer.

Energy return · %

Share of impact energy handed back to the ball. Higher plays livelier and more powerful.

Spin potential

Ball friction divided by string-on-string friction. Higher means better bite with a cleaner snapback, so more spin.

Ball bite · COF

String-on-ball friction. Higher grabs the ball harder through the brush.

Snapback · COF

String-on-string friction. Lower lets the mains slide and snap back into place after impact.
