Abstract
A safety device for bicycles, for preventing unscrewing, comprises a ring element which can be mounted coaxially on the outer ring of the upper steering bearing and on the lock nut to lock them in position on the tubular sleeve of the fork mounted rotatably in the steering tube of the frame. The ring element is clamped onto the ring of the bearing and the lock nut so as to prevent the accidental unscrewing of the lock nut. It also has a radial appendage which is adapted to act as an abutment for the end of the sheath of a flexible brake-operating cable.
