Secure locking thanks to innovative gravitation technology. The NutFix system protects wheels against would-be thieves. The nut is fitted with a mechanism that only releases the screw below when the bike is on its side. If the bicycle is locked upright, the Nutfix caps cannot be removed so bike components remain securely in place.
