NutFix Component Security
NutFix is the new and stylish solution for securing bicycle components. The NutFix system protects both wheels and the seat post against would-be thieves. Its real strength lies in its special functionality. The nut is fitted with a mechanism that only releases the screw below when the bike is on its side. This means it is not possible to access the screw unless the bike is on its side.
