The SpeedChain Neuromuscular Over-speed Device (NOS) is the latest product from the makers of the SpeedChain. It was developed to improve bat speed and swing efficiency by using variable resistance during the swing.
The NOS provides a feel that is unlike weighted bat sleeves, donut bat weights, and other on-deck devices that are the same weight through the swing. Most devices are heavy during bat acceleration - heavy through the hitting zone - and heavy during bat deceleration. Because of its unique design the NOS is lighter at acceleration - has maximum weight through the hitting zone - and becomes lighter during deceleration.
The device is end loaded with weight adjustment accomplished by changing the number of end chains. The device is a lightweight and portable training aid that can deliver a wide range of benefits through its use before practice or play.
