Polyester Gauge 17 1.25 mm In production

Lab measurements for Volkl Cyclone Tour 17 (1.25), 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

171lb/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

6.1

higher = more spin off the string bed

Ball bite

0.472COF

higher = grabs the ball harder

Snapback

0.078COF

lower = strings slide and snap back

How it ranks against all 789 strings

Stiffness 171 lb/in · 39th pct

Stiffer than 39% of strings tested.

Tension loss 53 % · 92nd pct

Sheds more tension than 92% of strings tested — goes dead fast, expect frequent restringing.

Energy return 83 % · 7th pct

Livelier than 7% of strings tested — very muted and low-powered.

Spin potential 6.1 · 81st pct

More spin potential than 81% of strings tested.

Ball bite 0.472 COF · 67th pct

Grips the ball harder than 67% of strings tested.

Snapback 0.078 COF · 19th pct

More string-on-string friction than 19% of strings tested.

More from Volkl

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.
