    摘要: 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.

    摘要: A bicycle front derailleur is basically provided with a base member and a movable member. The base member includes a bicycle mounting portion. The movable member is movably supported to the base member between a retracted position and an extended position relative to the base member. The movable member includes a first guide plate having a first inner surface and a second guide plate having a second inner surface. The first and second inner surfaces face each other to form a chain receiving slot therebetween. The second guide plate includes an adjustable guide member that is arranged at the chain receiving slot to move between at least two different positions relative to the second guide plate.

    摘要: The present invention relates to a chain guide device (10) for gravity or all-mountain bicycles comprising a frame (11) and a toothed chainring (12) on which the pedals are mounted.
    The chain guide device (10) is intended to be positioned coupled with the chainring (12) in such a way as to prevent the chain (14) of the bicycle from coming off the teeth of the chainring (12).
    The chain guide device (10) comprises: a top guide (20) intended during use to be positioned along the top portion of the chainring (12) and provided with a first groove (22); a bottom guide (30) intended during use to be positioned in the vicinity of the bottom portion of the chainring (12) and provided with a second groove (32); said top guide (20) and said bottom guide (30) being arranged on a support (40) by means of which the chain guide device (10) is fixed to the frame (11) of the bicycle.
    In accordance with the invention, the first groove (22) and the second groove (32) interact directly with portions of the chain (14) which are directly engaged with the chainring (12), coming into contact with the chain only if the chain tends to disengage from the teeth of the chainring.

    摘要: A bicycle structure (10) is provided with a crankset (14) and a front derailleur (16). The crankset (14) includes a plurality of chain rings (24, 26, 28), with a largest chain ring (24) of the plurality of chain rings having a plurality of teeth (24a) with teeth bottoms (24b) interposed between adjacent ones of the teeth. The front derailleur (16) includes a chain guide (32) having a chain guide slot (38) partially defined by a first chain engagement surface (41) with a protruding part (48) that protrudes outwardly from the first chain engagement surface (41) into the chain guide slot (38). The protruding part (48) is located away from the teeth bottoms (24b) of the largest chain ring (24) in a radial outside direction of the largest chain ring by a prescribed distance in a range from eight millimeters to sixteen millimeters or in a range from 90% to 190% of a maximum chain height of the chain.
