ABUS Nutfix Seatpost Clamp Nut Protection
Nutfix seatpost clamp locks are available for seat post sies 28.6, 30.0, 31.8
and 34.9mm diameter.
The Nutfix ingeniously uses gravity to lock the nut cover into place. The cover can only be lifted to reach the M8 nut underneath when the bike is placed on it's side. When the lock assembly is held at 90° perpendicular to the ground, the gravity controlled inner mechanism releases and allows the cover to be lifted. When the bike is upright and properly locked, it can not be placed on its side while the spinning cover prevents access to the release nut.
ABUS Nutfix are Made in Germany
