M2 Pro 125/16

Polyester Gauge 16 1.33 mm In production

Lab measurements for Luxilon M2 Pro 125/16, 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

182lb/in

lower = softer, kinder on the arm

Tension loss

53%

lower = stays where you strung it

Energy return

83%

higher = livelier, more free power

Spin potential

3.6

higher = more spin off the string bed

Ball bite

0.348COF

higher = grabs the ball harder

Snapback

0.098COF

lower = strings slide and snap back

How it ranks against all 789 strings

Stiffness 182 lb/in · 48th pct

Stiffer than 48% of strings tested.

Tension loss 53 % · 93rd pct

Sheds more tension than 93% of strings tested — goes dead fast, expect frequent restringing.

Energy return 83 % · 10th pct

Livelier than 10% of strings tested — very muted and low-powered.

Spin potential 3.6 · 21st pct

More spin potential than 21% of strings tested.

Ball bite 0.348 COF · 2nd pct

Grips the ball harder than 2% of strings tested — slick against the ball.

Snapback 0.098 COF · 61st pct

More string-on-string friction than 61% of strings tested.

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.
