Extension OC
Donic Extension OC is an exceptionally fast and hard offensive blade built for aggressive, uncompromising play. Its construction combines hard Ovankole outer plies with PBO fiber/carbon layers, delivering powerful acceleration and deep penetration. Engineered for professionals who dominate with quick, powerful strokes, the Ovankole wood—also used in guitar making—contributes to its rapid response. This blade stands as one of DONIC's fastest offerings, catering to a specialized, high-octane playing style.
This 7-ply construction features hard Ovankole outer plies for speed and stiffness, followed by PBO fiber/carbon layers for enhanced acceleration and a larger sweet spot. The inner plies of Ayous and a Kiri core provide a degree of stability and feel, creating a composite structure optimized for offensive performance.
TT Sensei Ratings
✦Our expert analysis of this blade's performance characteristics
Extension OC is consistently described as a very fast blade, with ratings aligning around 9.5-9.9. Its construction, featuring hard Ovankole outer plies and PBO fiber/carbon layers, is specifically designed to maximize speed and power for aggressive offensive play.
While primarily speed-oriented, Extension OC offers a respectable level of control, as indicated by user ratings averaging around 8.9. The composite layers and wood construction help maintain a degree of feel and manageability, though it requires skilled players to fully harness.
The hard Ovankole outer plies and the inclusion of PBO fiber/carbon layers contribute to a hard feel. This offers direct feedback on ball impact, characteristic of fast, offensive blades, providing a stiff sensation during play.
The combination of speed-focused materials and a stiff flex generally results in a medium-high throw angle. This allows for a good trajectory on aggressive topspin shots, enabling players to clear the net with pace and drive the ball deep into the opponent's court.
Due to its stiff construction and fast nature, Extension OC has a medium to short dwell time. This allows for quick exchanges and powerful, direct shots but requires players to be precise with their timing to generate spin effectively.
Extension OC is a stiff blade. This results directly from the hard Ovankole outer plies and the presence of carbon within the PBO fiber layers, which minimize flex and enhance power transfer for aggressive shots.
The combination of hard materials and fiber layers leads to medium vibration levels. While the PBO fiber may help manage vibrations and enlarge the sweet spot, the overall construction leans toward a more direct and less dampened feel.
The use of premium materials like Ovankole and PBO fiber, combined with consistent user ratings for consistency, points toward excellent build quality. The blade is designed for durability and consistent performance.
Technology
Donic Extension OC features a 7-ply construction that integrates PBO (Polybenzoxazole) fiber with carbon. PBO fiber is known for its high strength and elasticity, offering a larger sweet spot and enhanced stability. Combined with the hard Ovankole outer plies, this creates a blade that is exceptionally fast and powerful. The specific layering is designed to maximize acceleration and direct power transfer, catering to an aggressive, offense-oriented playing style.
