Head Radical Pro 2021 Tennis Racquet

The Head Radical Pro 2021 (Graphene 360+) marked a significant shift in the Radical series, moving toward a more classic "player's racquet" feel with improved flex and a thinner beam compared to its predecessor.

Key Technologies

1. Graphene 360+: Combines Head's signature Graphene 360 energy transfer with SpiralFibers in the lower hoop. This results in a cleaner impact feel and enhanced flex.
2. Control Pattern: A more dense 16x19 string pattern. By spacing the center strings more tightly, Head increased directional control while still allowing for modern spin levels.
3. Sound Grommets: Larger, rectangular grommets that allow for more string movement. This helps "open up" the sweet spot slightly and provides a more powerful sound and feel on impact.
4. Variable Beam: The cross-section varies in thickness to balance power, control, and stability across different parts of the frame.

On-Court Performance

1. Groundstrokes: It offers a "solid" and predictable response. While it's 5g heavier than the previous version, the head-light balance keeps it relatively maneuverable for its weight class.
2. Feel & Comfort: This 2021 update was widely praised for being more arm-friendly. The thinner beam and SpiralFibers reduced the "stiff" sensation found in earlier Graphene models.
3. Stability: The increased static weight and healthy swingweight provide excellent plow-through, making it very stable against heavy hitters.
4. Ideal Player: It is best suited for advanced (4.5+ NTRP) all-court players who generate their own power and prioritize precision and touch over raw "free" power.
