Immune OX Classic
Osp Immune OX Classic is a specialized defensive blade engineered for players who combine OX pips on one side with inverted rubber on the other. Its asymmetrical construction delivers distinct performance for each wing, offering exceptional control, disruptive spin reversal for the pips side, and a controlled offensive platform for the inverted side. The blade produces a low, flat trajectory ideal for blocking and chopping, making it a premier choice for tactical defenders and twiddlers seeking a lightweight, agile tool.
This asymmetrical 5-ply construction is the heart of the blade's performance. It pairs a harder wood layer (typically for the backhand/OX pips side) with a softer Limba layer (for the forehand/inverted side) on each face, sandwiching an Ayous core. This design creates two distinct feels and responses in one blade, optimizing it for a dual-rubber defensive style.

✦Our expert analysis of this blade's performance characteristics
Speed is moderate, prioritizing control for a defensive foundation. It’s not a slow blade, but raw pace takes a backseat to placement and disruption. Players report that pairing a faster inverted rubber on the forehand side can effectively counter an opponent's pace, allowing for controlled offensive shots when needed.
Control is the defining and paramount characteristic of this blade. Every aspect of its design prioritizes extreme precision in placement, blocking, and chopping. The exceptional feedback and feel allow for intricate, tactical shot-making, making it an elite choice for players whose game is built on consistency and disruption.
The feel is a deliberate blend, changing based on which side you strike with. The forehand side, built with softer Limba, provides a gentler, more dwell-oriented sensation. The backhand side, constructed from harder woods, delivers a sharper, more direct response. This dual nature supports distinct tactical approaches for each wing.
Throw angle is another dual-characteristic. The forehand side typically produces a medium-high arc, facilitating powerful loops. The OX pips backhand side, however, creates a characteristically low throw angle, ideal for producing flat, skidding shots and aggressive chops that stay close to the net.
Dwell time varies significantly between sides. The softer forehand side offers a longer dwell, beneficial for loading spin on loops and serves with inverted rubbers. Conversely, the harder backhand side designed for OX pips has a much shorter contact time, promoting direct, disruptive shots with less dwell.
Flexibility sits in a medium range, balancing the characteristics of its two sides. The softer forehand side allows for more flex during looping strokes, while the harder backhand side remains stiffer for direct blocking and chopping. This balance is key to its versatility for combination play.
Vibration is well-dampened, contributing directly to the blade's legendary control and comfortable feel. This muted feedback allows players to maintain consistent touch and precise placement, which is especially valuable during extended defensive rallies and delicate blocks.
OSP's reputation for high-quality, handmade craftsmanship is fully realized here. The blade features an immaculate finish and the use of premium, carefully selected wood materials. This commitment to quality ensures not only a consistent and reliable performance but also notable durability for long-term play.
Technology
The Osp Immune OX Classic embodies OSP's philosophy of high-quality, handmade blades through its unique asymmetrical construction. This is its core technological innovation: a meticulous layering process that isolates performance properties for each side of the racket. By strategically placing softer woods like Limba on the forehand and harder woods like Mahogany or Walnut on the backhand, the blade creates two optimized platforms. This specialization ensures the OX pip side delivers maximum disruptive effect and control with a sharp feel, while the inverted side offers enhanced dwell time and offensive potential. The entire design also emphasizes a lightweight build for superior agility and effortless twiddling.
Similar Blades
OSP Immune OX
The OSP Immune OX is a closely related predecessor, also designed for push-blocker styles with OX pips. It shares a focus on lightweight design and disturbing effect. TTSensei experts note the 'Classic' variant appears to offer a more refined asymmetrical feel, potentially providing a slightly different, perhaps more controlled, performance profile for the inverted rubber side.
OSP Immune Active DEF Pro
The Immune Active DEF Pro is considered a blade that the Immune OX Classic was developed to improve upon. Players report the Active DEF Pro is generally heavier and harder. The Immune OX Classic thus presents itself as a lighter, more controlled, and potentially more maneuverable alternative for defenders who found its predecessor too demanding or less precise.
