Volkl V-Fuse is a premium hybrid tennis-string set that combines V-Icon natural gut with Cyclone, Volkl’s twisted ten-sided co-polyester. It is designed to blend natural-gut power, comfort and tension stability with the spin and control of a shaped polyester.
The package can be installed in two meaningful orientations. V-Icon mains with Cyclone crosses create a comfort-led hybrid with controlled power, while Cyclone mains with V-Icon crosses create a firmer, spin-led response for established polyester users.
Within Volkl’s range, V-Fuse is the performance alternative to the softer V-Blast gut-and-multifilament hybrid. It best suits intermediate and advanced players who generate their own racket-head speed but do not want a complete polyester stringbed. The Tennis String Finder can help compare the available material combinations.

Material and Construction
V-Icon is a coated natural gut made from natural serosa fibers. Its elastic structure provides energy return, pocketing and exceptional tension maintenance compared with most synthetic strings.
Cyclone is a firm co-polyester monofilament with a twisted ten-sided profile. The geometric surface increases ball interaction, while the smooth-enough movement of the strings supports snapback when the stringbed remains fresh.
The two materials have very different stiffness and wear behavior. Natural gut stays resilient but can fray and notch, while Cyclone resists breakage yet gradually loses tension and elasticity. The useful life of the hybrid depends on how these changes interact.
Orientation determines which material dominates. Main strings normally shape more of the response, so a gut-main installation should not be described as identical to a Cyclone-main installation.
Volkl V-Fuse Performance
Power
V-Fuse provides useful power without the unrestricted rebound of a complete natural-gut stringbed. The V-Icon half supplies easy depth and elasticity, while Cyclone adds a firmer counterbalance.
With V-Icon in the mains, power is readily accessible to compact, moderate and fast swings. Cyclone mains produce a lower-powered response that expects the player to create pace with a committed swing.
The hybrid therefore covers a wider range of swing styles than full polyester, but orientation must be selected honestly. Players wanting maximum free power should not place Cyclone in the mains merely because that setup sounds more durable.
Power rating: 8.5/10
Spin
Spin is one of V-Fuse’s main strengths. Cyclone’s twisted ten-sided profile adds ball interaction, while the contrast between gut and polyester can promote useful string movement.
Cyclone mains emphasize direct bite and a firmer launch. V-Icon mains rely more on pocketing and snapback against the polyester crosses, creating spin with a more elastic response.
The shaped polyester can notch the natural gut over time. Once the strings stop returning to position or Cyclone’s edges have worn, the original spin level will decline even if neither component has broken.
Spin rating: 8.5/10
Control
Control is excellent when the orientation matches the player. Cyclone reduces launch and supports aggressive acceleration, while V-Icon maintains tension and adds more nuanced feedback than a complete polyester setup.
Cyclone mains create the most contained trajectory and suit advanced baseliners. V-Icon mains are livelier but remain more predictable than many soft hybrids because the polyester crosses moderate rebound.
Control can deteriorate when the polyester loses elasticity or when notching prevents the mains from moving. Physical survival alone does not guarantee that the hybrid is still performing as designed.
Control rating: 9/10
Comfort and Feel
V-Fuse is significantly more comfortable than a full bed of Cyclone, especially with V-Icon in the mains. Natural gut stretches readily and cushions the firm response of the polyester component.
The gut-main orientation feels more pocketing, powerful and nuanced. Cyclone mains feel crisper and firmer, with the gut crosses adding some cushioning without completely changing the polyester-led character.
This remains a setup containing polyester. Players with persistent arm symptoms should not assume that the natural-gut half makes every orientation appropriate, and equipment cannot replace qualified medical advice.
Comfort rating: 8.5/10
Durability and Tension Maintenance
Physical durability is moderate and highly dependent on orientation. Cyclone is resistant to breaking, but its shaped surface can saw into V-Icon at the intersections.
With V-Icon mains, fraying and notching of the gut are usually the main physical limits. With Cyclone mains, the polyester may notch and cut the softer gut crosses while also losing useful elasticity before it breaks.
Tension maintenance is better than a complete polyester setup because natural gut retains elasticity exceptionally well. However, V-Icon cannot prevent Cyclone from becoming less responsive with time.
Replace the hybrid when launch changes materially, the strings stop snapping back, Cyclone feels unresponsive or the natural gut is deeply notched. A stringbed can remain intact after its useful playability has ended.
Choosing the Right Gauge
| Package | General characteristics |
|---|---|
| 16 gauge | More stability and resistance to notching, with a firmer response |
| 17 gauge | More feel, spin and response, with faster wear |
The 16-gauge version is the safer starting point for open patterns, heavy topspin and players concerned about the natural-gut component wearing quickly.
The 17-gauge package works well in dense patterns and for players who restring before breakage. Retail listings should be checked because package details can vary by region.
Full Bed or Hybrid Setup
V-Icon Mains With Cyclone Crosses
This orientation maximizes natural-gut power, comfort, feel and tension stability. Cyclone crosses reduce launch and help the gut mains move and return after impact.
It is the better choice for players transitioning away from full polyester or prioritizing a more forgiving response. Careful installation and smooth, undamaged grommets help protect the gut.
Cyclone Mains With V-Icon Crosses
Cyclone mains dominate spin, control and firmness. V-Icon crosses add power and cushioning, but less of the gut’s distinctive elasticity reaches the response than when it is installed in the mains.
This setup suits experienced polyester users with long, fast swings. It should not be chosen solely to make the gut last longer, since shaped-polyester mains can still wear through soft crosses.
Using Either Component in a Full Bed
A full bed of Volkl Cyclone maximizes shaped-polyester control and durability but is considerably firmer. A full bed of Volkl V-Icon maximizes comfort, power and tension stability at a higher cost.
One V-Fuse package contains half sets for a hybrid, so it does not provide enough of either component for a complete full bed.
General Tension Guidance
The starting point should reflect orientation and the player’s previous material. A gut-main setup can begin near an established natural-gut or hybrid reference, while a Cyclone-main setup should respect the firmer polyester response.
Lower tension adds pocketing, power and launch. Higher tension increases initial containment but can reduce comfort, stress the gut and make Cyclone feel unnecessarily rigid.
Large differences between the mains and crosses are not automatically beneficial. Stay within the racket manufacturer’s range, account for pattern and head size, and adjust in small steps. The Tennis String Tension Calculator offers broad guidance rather than a universal prescription.

Volkl V-Fuse Compared With Other Strings
V-Fuse vs Volkl V-Blast
Volkl V-Blast combines V-Icon with V-Feel multifilament. V-Blast is softer and more powerful, while V-Fuse provides more spin, control and containment.
V-Fuse vs Volkl Cyclone
A full bed of Cyclone is firmer, less powerful and less expensive. V-Fuse adds natural-gut elasticity, feel and tension stability while retaining the shaped polyester component.
V-Fuse vs Babolat RPM Blast and Natural Gut
Babolat RPM Blast and natural gut follows the same broad shaped-polyester and gut concept. The specific profiles and responses differ, but orientation has the same fundamental importance in both hybrids.
V-Fuse vs Wilson Champion’s Choice
Wilson Champion’s Choice combines premium natural gut with ALU Power Rough. Both target experienced hybrid users, while V-Fuse uses the more aggressively shaped Cyclone component.
Final Verdict
Volkl V-Fuse is a versatile premium hybrid that legitimately changes character when its orientation changes. V-Icon mains produce the more powerful and comfortable setup, while Cyclone mains favor spin, control and a firmer tournament response.
Its main limitations are cost, installation care and the interaction between shaped polyester and natural gut. The package is not automatically durable simply because half of it is polyester, and Cyclone can lose useful elasticity before it breaks.
For intermediate and advanced players who understand those tradeoffs, V-Fuse offers a well-balanced route between full natural gut and full polyester. The 16-gauge package is the safest starting point, while 17 gauge favors dense patterns and players who restring regularly.
