I have a 100 lb Ringside thai bag and as I was working the bag the other day the spring attached to the ceiling mount snapped. I'm not sure which end the piece that broke was attached to (bag chain or ceiling mount) because it happened suddenly. So I examined the spring and mount and noticed that the eyebolt on the mount is worn down creating sharp edges. I've had it for one year, but that's not normal, right? Here are some pics: I have this mount: http://store.titlemma.com/rafheavbahang.html and this spring: http://www.gungfu.com/htm-training-...cessories-bag-heavy-bag-shock-spring-coil.htm Has anyone else had this happen or have an idea as to what caused it?
