ABSTRACT:
A bicycle handlebar attachment includes a stem adapted at one end for connection to the head tube and having an eyelet at its opposite end for receiving the handlebar crossbar. The eyelet is divided by a slit into two jaws, one of which defines a threaded blind hole and the other of which has a partially-threaded through-hole aligned with the blind hole for receiving a screw for clamping the jaws together to tighten the eyelet on the crossbar. When the screw is released from the blind hole, an abutment plate can be inserted in the slot and the screw tightened aginast it to force the jaws apart to allow the crossbar to be inserted in or removed from the eyelet.
