This 11-inch (approx. 28cm) replacement bladder is specifically designed for larger, heavy-duty double-end bags, offering a more stable target and a powerful rebound. Perfect for those who prefer a slightly larger surface area for practicing power shots alongside timing, this bladder restores the structural integrity and "snap" to your floor-to-ceiling ball. Key Features Precision 11-Inch Fit: Custom-sized for larger 11-inch diameter casings, ensuring the bladder fills the entire internal cavity to prevent "dead spots" or lopsided movement. Heavy-Duty Latex/Butyl Blend: Crafted from extra-thick materials to handle the higher air volume of an 11-inch bag, providing a firm, consistent surface that won't soften mid-workout. Maximum Air Retention: Features an upgraded leak-proof valve system that maintains high pressure for longer, so you can spend more time hitting and less time pumping. Enhanced Durability: Reinforced at the seams to withstand the increased tension and vibrational stress common in larger-sized bags. Rapid Rebound: Engineered for high-elasticity response, giving you a predictable, rhythmic return that is essential for mastering slips, ducks, and long-range punching. Ideal For Large Professional Bags: The go-to replacement for 11-inch leather or synthetic floor-to-ceiling units. Power & Speed Work: Offers enough resistance for heavy hitters while remaining responsive enough for rapid-fire combinations. Gym Maintenance: A cost-effective way to refresh high-use equipment without replacing the expensive outer shell. Maintenance Tip: To ensure the longest life, always use a moistened pump needle when inflating to protect the valve seal from tearing. ide
