Compositemaster I 16

Nylon Gauge 16 1.28 mm In production

Lab measurements for Gosen Compositemaster I 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

165lb/in

lower = softer, kinder on the arm

Tension loss

21%

lower = stays where you strung it

Energy return

92%

higher = livelier, more free power

Spin potential

4.2

higher = more spin off the string bed

Ball bite

0.345COF

higher = grabs the ball harder

Snapback

0.083COF

lower = strings slide and snap back

How it ranks against all 789 strings

Stiffness 165 lb/in · 33rd pct

More from Gosen

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.
