Good speed bag bladder
Size: Small
Durable Material – High-quality bladders made from latex or rubber offer excellent responsiveness and longevity. Consistent Air Retention – A well-made bladder holds air well, reducing the need for frequent reinflation. Fast Rebound – A properly inflated bladder provides a quick, snappy bounce, essential for effective speed bag training. Easy to Install – Most bladders can be swapped out in minutes, bringing an old speed bag back to life. Universal Fit Options – Many brands offer multiple sizes to fit different speed bags. ... show more

Perfect
Size: Medium
Perfect for my cheap Century speed bag that was leaky from day 1. Unlike my vintage Everlast bags, the Century was not designed for ease of bladder replacement, but hats off to Forza for making a strong and flexible replacement bladder that I managed to work in place, glue around the valve stem, and line up the valve hole, not perfectly but adequately. I chuckled at the description saying low cost enough to keep 2 or 3 extras for emergencies because I thought I was the only one who would consider a leaky speed bag an emergency, so I might just do that because these bladders are of the quality to merit use on my high value 1970s vintage Everlast bags if such an emergency arises. ... show more

Looked small at first, but fit perfectly into my bag
Size: Small
Be nice if it had stick on near the air valve so it would fixate in the bag

Quality, thick material
Size: Medium
The bag did not fill entirely at first, I thought oh well, for the price, it's still usable. Left it on the side for a few days, when I picked it up again, I was surprised it pumped up more to rock hard. I put the bag down again and for a few days it held the air. One week later, the bag is still rock hard, pretty amazing product. ... show more

Poor Quality
Size: Small
We have 5x7” and 4x6” speed bags and use them 4 days/week and these bladders are cheap and leak readily usually from the valve. They’re inexpensive comparatively for a reason but if you don’t mind replacing the bladders every 2 months then this might be for you. Otherwise if you don’t want the hassle then buy better quality. ... show more
