One piece shift lever mount adapter for a bicycle

A shift lever mount for supporting a gear shift lever adjacent a sharp curve on a curved road style bicycle handlebar having an existing hand brake lever mount thereon useful for securing said shift lever mount adjacent the hand brake lever mount on the handlebar,

• said shift lever mount comprising,
• an attachment collar having a center opening defined by an annular wall with said center opening sized so as to allow said attachment collar to be placed around the handlebar, said annular wall having a longer length in a first area and a shorter length in a second area so as to allow said attachment collar to be positioned in the sharp curve in the handlebar and in close proximity thereto with said shorter length of said annular wall positioned in an inside smaller radius of the sharp curve and said longer length positioned in an outside longer radius of the sharp curve in the handlebar, said annular wall being sufficiently thin in nature so as to allow said attachment collar to be at least in part placed underneath the hand brake lever mount whereby tightening of the hand brake lever mount compresses and stabilizes said attachment collar against the handlebar,
• an extending member affixed to said annular wall of said attachment collar and extending therefrom generally toward an opposite side of the handlebar, said extending member including at least one angular change over its length,
• a shift lever attachment stud affixed to a distal end portion of said extending member, said attachment stud including a distal end having a threaded bore for receiving a mounting fastener for affixing the gear shift lever onto said attachment stud, said attachment stud further including an anti-spin means sized and shaped for insertion into a receiving means in a base of the gear shift lever for preventing the base of the gear shift lever from spinning on said attachment stud,
• said extending member being of a length which in combination with said at least one angular change in said extending member positions said attachment stud with said threaded bore opening generally toward said attachment collar so as to allow said shift lever mount to support the gear shift lever a distance away from said attachment collar equal to about a human thumb length so as to position the gear shift lever a distance from the handlebar sufficient to allow the gear shift lever to be actuated by an extending thumb of a hand grasping the handlebar adjacent said attachment collar,
• said extending member further including at least one elevational change over its said length with said elevational change providing for unobstructed access to the mounting fastener of the gear shift lever by an elongated wrenching tool,
• a shift cable housing support attached to said extending member and positioned for supporting a shift cable within a shift cable housing in approach toward said attachment stud and the gear shift lever.
