As illustrated, A designates a substantially U-shaped bar; B, a transverse brace bar; and C, the _
means by which the handle bar is- secured with

The bar A may be formed of' metallic tubing
and is substantially U-shaped. It comprisesthe _
' To attach the improved structure to the steer
ing shank of a bicycle or motorcycle, the center`
knurled portion of brace bar B _is placed between
the jaws 38 and` 32 of the clamping means and
bolts 33 and 34 inserted. Then the shank 30a 35
ofthe connecting means is inserted into the hol
