Abstract

Apparatus is for, or is included with, a vehicle having a vehicular handlebar, and also having first and second pipe portions. The first elongated portion is configured to receive and support a vehicular handlebar, and to be slidably received, at least in part, in the second elongated portion. An engagement device is configured to selectively engage the first and second pipe portions with each other. The engagement device, in use, prevents the first and second pipe portions from rotating relative to each other. The engagement device is also configured to selectively disengage the first and second pipe portions from each other. The engagement device, in use, permits the first and second pipe portions to rotate relative to each other. A clamp assembly is configured to selectively clamp the first elongated portion and the second elongated portion with each other.
