Definition:
Rollers are tiny pulleys used in place of grommets where strings pass through the frame. They allow the strings to move freely around the string-frame intersection, so that when a ball hits a string, more of the impact force is distributed from that string to its neighbors. In effect, the stringbed acts more like one big string that gets stretched with each ball impact. The stringbed compresses farther, which increases the trampoline effect, making the stringbed livelier. More importantly, it spreads the shock of the ball impact over a longer period of time, reducing the severity of the shock at any given moment.
