Experience a perfect training with the Balazs® Lightning™ Gyro Speed Bag. This Speed Bag comes with a replaceable bladder. The Balazs® Lightning™ Speed Bag is made of top grain leather for super smooth and controlled strikes and a tight top loop, for excellent rebounds and control. The die-stamped leather panels are all of the exact same size for perfect balance. No welting at the seams to throw your strike off, or scrape your knuckle. It features Balazs® Super Valve for holding air and a replaceable rubber bladder. This light-weighted speed bag gives you a crisp response.

It's available in four sizes: Peanut (Extra Small, 8 inch x 5 inch), Sonic (Small, 9 inch x 6 inch), Jet (Medium, 10 inch x 7 inch), Rocket (Large, 11 inch x 8 inch).
