Bicycle gear shifter having separate shift control members for cable pull and release
摘要:
A shifting device including first and second shift control members, a takeup element, a holding member, and a release member. The takeup element configured for winding and unwinding a tensioned control cable. The first control member is rotatable about a handlebar and configured to rotate the takeup to at least pull or wind the control cable onto the takeup. The second control member is a return-to-neutral member for rotating the takeup to release the. The holding member is rotatable with the takeup and retains the takeup in select angular positions. The release member is operable for disengaging the holding member in response to the actuation or return stroke of the second control member for allowing the takeup to unwind the cable a sufficient amount to enable a single gear shift.
