Who Is the Ultra 103S For?
Intermediate and Developing PlayersThe Ultra 103S is tailor-made for players advancing past the beginner stage. Its 103 sq in head size offers a slightly larger sweet spot than standard frames, making it easier to generate clean contact and consistent depth.
Spin-Oriented BaselinersWith its open 16x15 string pattern, this racket is a dream come true for players who rely on topspin or slice. Whether you're hitting heavy topspin forehands or kicking up unpredictable serves, the Ultra 103S amplifies spin potential with minimal effort.
Recreational and League PlayersFor club-level competitors and weekend warriors, the Ultra 103S provides performance without being too demanding on the arm or body. It’s a great fit for players who want to play frequently without sacrificing comfort or control.
Performance Features
Spin Effect TechnologyThe Ultra 103S features Wilson’s signature Spin Effect Technology — an open 16x15 string pattern that increases ball rotation on contact. The extra spin allows shots to dive quickly into the court, making them harder for opponents to handle. It's an ideal weapon for baseline players who want to control points through depth and kick.
Generous Head SizeThe 103 sq in head size provides a forgiving hitting surface, increasing consistency and reducing mishits. This larger sweet spot also gives the racket a more comfortable feel on off-center strikes, ideal for players refining their technique.
Power with PrecisionDespite being slightly lighter than pro tour rackets, the Ultra 103S delivers solid power from the baseline. Its firm beam construction and extended dwell time offer an energetic response, allowing players to hit confidently while still controlling their shot placement.
Net Play and VolleysAt the net, the Ultra 103S feels stable and maneuverable. Its slightly head-light balance allows for quick reactions and clean volleys. Players who like to mix in drop shots, angled volleys, or sudden net rushes will enjoy the racket’s responsiveness.
Serve PerformanceOn serves, the Ultra 103S shines with excellent spin potential and racquet-head speed. The open string pattern helps kick serves jump up off the court and adds movement to slice serves, giving players extra variety to disrupt returners.
Comfort and Feel
Comfort is another strength of the Ultra 103S. The graphite composite construction provides a stable yet flexible feel, which reduces vibration on impact. The result is a racket that performs well without punishing your arm or wrist — a common concern for players returning from injury or playing multiple times a week.
The frame’s stiffness is moderate, offering a good balance between power and comfort. It feels lively, without being overly stiff or jarring.
Design and Aesthetic
The Ultra 103S features a bold and modern look. Its clean design lines and subtle detailing give it a sleek, confident presence on the court. The slightly thicker beam offers a powerful silhouette, signaling the racket’s ability to generate explosive shots while maintaining precision and flair.

Use spin-friendly strings (like polyester or hybrid setups) to enhance the Spin Effect performance

Replace the grip or add an overgrip suited to your hand size and sweat absorption preferences
