Gamma

TNT2 Tour 17 (1.27)

Nylon Gauge 17 1.27 mm In production

Lab measurements for Gamma TNT2 Tour 17 (1.27), 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

155lb/in

lower = softer, kinder on the arm

Tension loss

20%

lower = stays where you strung it

Energy return

92%

higher = livelier, more free power

Spin potential

4.5

higher = more spin off the string bed

Ball bite

0.454COF

higher = grabs the ball harder

Snapback

More from Gamma

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.
