Lab measurements for Volkl Cyclone Tour 18 (1.20), 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

159lb/in

lower = softer, kinder on the arm

Tension loss

51%

lower = stays where you strung it

Energy return

85%

higher = livelier, more free power

Spin potential

7.8

higher = more spin off the string bed

Ball bite

0.572COF

higher = grabs the ball harder

Snapback

0.073COF

lower = strings slide and snap back

How it ranks against all 789 strings

Stiffness 159 lb/in · 25th pct

Stiffer than 25% of strings tested.

Tension loss 51 % · 91st pct

Sheds more tension than 91% of strings tested — goes dead fast, expect frequent restringing.

Energy return 85 % · 18th pct

Livelier than 18% of strings tested.

Spin potential 7.8 · 96th pct

More spin potential than 96% of strings tested — elite spin generation.

Ball bite 0.572 COF · 93rd pct

Grips the ball harder than 93% of strings tested — bites the ball hard through the brush.

Snapback 0.073 COF · 9th pct

More string-on-string friction than 9% of strings tested — slides and snaps back freely.

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.
