Manually height adjustable and rotatable steering assembly for bicycles

A method for rotating the steering assembly of a bicycle having a front wheel fork with an integral upwardly extending steerer tube, headset bearings coaxial with said steerer tube, a handlebar assembly including a stem having a vertical member and slideably mounted inside said steerer tube, the vertical member of said stem has a section, exclusive of any slots or protrusions, that is a non-round cross sectional shape, said steerer tube being fitted with a restraining device to permit axial movement between said stem and said steerer tube, wherein said stem is manually adjustable in height in one position of said restraining device and the steerer tube is fixed onto said stem when said restraining device is in a second position, said method comprising the steps of:

• unlocking said restraining device and then performing a second action which then allows said steering assembly to be rotated about the steering axis to be approximately parallel with the front wheel of the bicycle.

A steering assembly for a bicycle comprising;

• a front wheel fork having an integral upwardly extending steerer tube, a handlebar assembly including a stem slideably mounted inside said steerer tube, headset bearings coaxial with said steerer tube, wherein said stem is rotatable about the steering axis by manually releasing said stem from said steerer tube such that said handlebar is positioned approximately parallel to the front wheel of the bicycle.

A steering assembly for a bicycle comprising;

• a front wheel fork having an upwardly extending steerer tube, a handlebar assembly including a stem mounted on the outside of an upper end of said steerer tube and a manually operated restraining device for coupling said stem to said upper end of said steerer tube.

A steering assembly for a bicycle comprising;

• a front wheel fork having an upwardly extending steerer tube, a handlebar assembly including a stem slideably mounted inside said steerer tube, headset bearings coaxial with said steerer tube, whereby said handlebar assembly is manually rotatable such that said handlebar is positioned approximately parallel to the front wheel of the bicycle.

A steering assembly for a bicycle comprising;

• a front wheel fork having an upwardly extending steerer tube, a handlebar assembly including a two part stem wherein the first part of said stem is slideably mounted inside said steerer tube and the second part of said stem is located exterior to said steerer tube, wherein said first part of said stem is rotatable relative to said second part of said stem.

A steering assembly for a bicycle comprising;

• a front wheel fork having an upwardly extending steerer tube, a handlebar assembly including a two part stem wherein the first part of said stem is slideably mounted inside said steerer tube and the second part of said stem rotates about said first part of said stem at a point other than on the steering axis of the bicycle.
