ABSTRACT:
An easy to operate control means for shifting gears on dual shift bicycles is described. The control means is constructed so that the front and rear derailleurs of a dual shift bicycle are controlled together to shift to any selected gear from any engaged gear with a single operator action. The design permits the operator to preselect the new gear to be used while continuously pedaling in the present gear, with the actual gear change being made at the operator's discretion. The design also facilitates a rapid series of up shifts or down shifts without requiring intervening gear selections.
