Kryptonite Gravity WheelNutz
Best security upgrade for urban cyclists protecting wheels from opportunistic theft.
A clever, keyless security solution that uses gravity to keep wheels locked while the bike is upright. It eliminates the need for extra cables or keys, relying on the simple physics of turning the bike upside down to release the nuts.
