A bicycle auxiliary brake control assembly which is provided on a bicycle body in a path of a double type control cable extending from a brake lever assembly to a brake assembly and including an outer cable and an inner cable, the outer cable being divided into two separate sections each having a divided end, wherein the auxiliary brake control assembly comprises a fixed member engaging with the divided end of one section of the outer cable at a fixed position, and an operating member engaging with the divided end of the other section of the outer cable and movable to enlarge and reduce the distance between the divided ends of the respective sections of the outer cable.
Claims21
A bicycle brake control system for a bicycle dropped handlebar, said handlebar including a pair of dropped side portions, and an intermediate straight portion extending between said pair of dropped side portions and centrally supported by a bicycle handle stem, said straight portion having first and second portions separated by said bicycle handle stem, said control system comprising:
- a main brake control assembly mounted on each of said dropped side portions and connected to a remote brake assembly through a double type control cable, said double type control cable including an inner cable guided in an outer cable, said outer cable being divided into two separate sections each having a divided end;
- and
- an auxiliary brake control assembly associated with said main brake control assembly and acting on said divided outer cable;
- wherein said auxiliary brake control assembly comprises:
- a fixed member engaging with the divided end of one section of said outer cable at a fixed position;
- an operating grip rotatably fitted on each of said first and second portions of said intermediate straight portion and engaging with the divided end of the other section of said outer cable to bring said divided end of said other section toward and away from the divided end of said one section upon rotation of said grip;
- said fixed member is in the form of a ring fixed on said straight portion of said handlebar and having a projecting non-movable engaging portion for engagement with the divided end of said one section of said outer cable while allowing passage therethrough of said inner cable;
- and
- said grip has a projecting movable engaging portion opposed to said non-movable engaging portion of said ring for engagement with the divided end of said other section while allowing passage therethrough of said inner cable, said movable engaging portion coming into surface contact with said non-movable engaging portion when said grip assumes a non-braking rotational position.
A bicycle brake control system for a bicycle dropped handlebar, said handlebar including a pair of dropped side portions, and an intermediate straight portion extending between said pair of dropped side portions and centrally supported by a bicycle handle stem, said straight portion having first and second portions separated by said bicycle handle stem, said control system comprising:
