The NutFix™ is ABUS’ innovative solution to preventing component theft. The Nutfix quick release set comes as a pair and ensures that your wheels don't disappear while while you are away.
The nut is fitted with a protective cover that only releases when the bike is on its side. This means it is not possible to access the nut unless the bike is on its side. The bike can then be returned to an upright position for any maintenance that is needed.
