easy to install & use

The Gravity Line skewers & nuts can be installed easily in place of existing skewers and nuts. They don't require any special keys, just a standard hex key or a wrench. A gravity pin is moved so that the nuts/skewer cannot be opened when the bike is upright. When the bike is turned upside down, the pin moves and the nuts/skewer can be loosened.
