Patent number: 9919765Abstract: Embodiments of a front derailleur gear shifting system including various unique chain guides attached to and operating from a single pivot point. This derailleur system provides a simple, yet, elegant and robust improvement in shifting technique over conventional, lateral motion front derailleurs. Embodiments of open and closed annulus chain guides having specially shaped lifting and pulling surfaces for acting upon a bicycle chain during shifting are also disclosed. Additionally, as an optional enhancement, a dual-sided chain catcher that prevents unintended over-shifts in either direction is disclosed.Type: GrantFiled: March 17, 2014Date of Patent: March 20, 2018Assignee: Wick Werks, LLCInventors: Christopher A.
