Highlights
What makes this racket stand out
Hypersoft foam core specifically calibrated for play above 25°C, where standard EVA goes mushy and loses pop
Elbowcare damping channel runs the full perimeter of the frame, reducing the vibration spike on blocked volleys
3D Carbon Cube face delivers stiff, direct ball exit despite the soft core — unusual pairing at this level

Our verdict
What the shape, core and construction tell us about how this racket is built to play.
The short version
The LW Cube Elbowcare S is for the advanced right-side player who has either had elbow trouble or is one bad summer away from it, and who refuses to compromise on a carbon face to get comfort. What it does that the specs don't show: it keeps the crispness of a carbon-faced control racket while genuinely reducing the post-match ache in the forearm. The trade-off is overhead finishing power — this isn't the racket to switch to if you're moving from the right to the left.
Strengths
Advanced control players on the right side who need fast reactions at the net without arm fatigue
Experienced players with a history of elbow sensitivity who refuse to trade down to a beginner-level soft racket
Keep in mind
Left-side attackers chasing put-away power from the back glass — the round head and soft core cap the ceiling overhead
How it's built to play
The LW Cube Elbowcare S sits in an unusual corner of the market: an advanced-level round racket built around joint protection rather than power. Most rackets that prioritise elbow comfort drop the player back to fiberglass and beginner-friendly weights. This one keeps the carbon face, keeps the medium balance, and engineers damping into the frame itself. The S suffix matters — this is the summer version, with a softer core calibrated for temperatures above 25°C where harder rubbers go mushy.
The face is Carbon Cube, Varlion's 3D-woven carbon fabric exclusive to the REGA line — it sits stiffer than standard weaves and gives the ball a cleaner, more direct exit despite the soft foam underneath. Underneath sits the Hypersoft core, deliberately tuned soft so it firms up rather than dies in summer heat. The pairing is the point: a stiff outer skin for response, a soft inner for absorption.
The Elbowcare system is the headline tech — a damping channel that runs from the handle through the entire frame perimeter, dispersing the vibration spike that normally travels up the arm on blocked volleys. The Prisma frame profile cuts roughly 10% of air drag versus a round tube, and the new Diffuser Wings insert — a clip-in, replaceable part — channels air through the heart and adds further vibration absorption at the bridge. The Summum 14.5cm handle adds reach for two-handed backhands; the Slice texture is moulded into the face rather than printed, so spin grip survives heavy use.
"Carbon Cube stiffness over a soft Hypersoft core: the face gives you directness, the core gives you comfort — they're working in opposite directions and that tension is what makes this racket interesting."
On court the racket behaves like a control round should — generous sweet spot, predictable on resets, fast through the air for a 350–365g frame. What separates it from a standard round is the impact signature. Blocked volleys at the net, the shot most likely to inflame an elbow, come back muted; the Elbowcare frame absorbs the shock rather than transmitting it up the wrist. The Carbon Cube face keeps the ball exit crisp, so you're not paying for that comfort with a dead, spongy feel.
"Blocked volleys come back muted rather than ringing — that's what Elbowcare damping through the full perimeter actually sounds like in play."
The limitation shows up overhead. A round head and medium balance don't generate the finishing power a diamond gives you on smashes, and the soft summer core compounds that. As a right-side racket in summer matches, it's hard to argue with. As a left-side attacker's primary weapon, you'll feel the ceiling.
FAQ
Should I choose the LW Cube Elbowcare S or the W version?
The S (Summer) has a softer core tuned for play above 25°C, where heat would otherwise soften a standard rubber too much. The W (Winter) is firmer, calibrated for cooler conditions below 25°C. If you can carry both, do — if you only buy one, pick the version that matches the climate you play in most. Players in southern Spain, Dubai or year-round indoor heat lean S; northern Europe outdoor leans W.
How does the LW Cube Elbowcare S 2025 compare to the Bourne Cube Elbowcare S?
Both share the same Elbowcare damping system, Carbon Cube face and REGA construction, so the elbow protection story is identical. The LW is the lighter, more maneuverable round of the two — built around control and reaction speed. The Bourne sits with a slightly more aggressive profile for players who want more weight behind the ball. Right-side control players choose LW; players who want more punch from a round shape look at Bourne.
Is this really an advanced racket if it's a round shape with a soft core?
Yes — and that combination is deliberate. The Carbon Cube face is stiff and gives the direct feedback advanced players need; the soft core and Elbowcare frame handle vibration. A beginner would get more value from a cheaper fiberglass round, because they can't exploit the stiff carbon face. This racket is built for an experienced player whose body has started asking questions of their equipment.
Will the Elbowcare system actually help if I have tennis elbow?
The Elbowcare channel is designed to absorb vibration along the full frame, which lowers the impact spike on shots like blocked volleys — the movement most associated with lateral epicondylitis flare-ups. It reduces a known risk factor; it does not cure an existing injury. If you're actively recovering, consult a physio before returning to play, and combine the racket with grip overgrip choices and technique work.
Why does the temperature rating matter so much on this racket?
Foam cores change behaviour with heat — they soften when hot and stiffen when cold, which shifts both power and feel. Most rackets are tuned for one window and play noticeably differently outside it. The Cube Elbowcare line splits the difference into two versions so the rubber behaves consistently in its target climate. If you play almost exclusively in summer heat, the S keeps the core feeling the way it was designed to feel.
