ABSTRACT:
A touring bicycle handlebar and reversible brake adaptor lever comprising of a handlebar having straight bar lengths extending equidistantly on each side of the handlebar boss providing the cyclist with the means to assume a hands on semicrouched posture, each straight bar length terminated by bent portions extending the bar upwardly above the level of the first straight portions to second straight portions with further bent portions extending the bar forwardly and downwardly, providing the cyclist with the means to assume a hands on upright posture, with third straight portions providing a means for mounting the brake lever assemblages, the third straight portions terminated by bending the bar backwardly to provide straight portions that extend beyond and below the first straight portions providing the cyclist the means to assume a hands on crouched posture and of a brake lever to replace the levers of the drop racing handlebar brake assemblages permitting the mounting of the modified assemblages on the touring handlebar so as to project toward the cyclist with the lever handle paralleling the straight bar length portions at the level of the handlebar boss where they can be grasped simultaneously for brake operation. The resultant positioning of the brake adaptor lever centrally in the assemblage mounting bracket minimizes the operational stress on the mechanism and permits the projection of the assemblage toward the cyclist reducing the required size of the lever to a minimum.
