Patent ID: 7722486

Claim:
A top/bottom pull bicycle front derailleur comprising: a base member configured to be coupled to a portion of a bicycle frame, the base member including a front mounting flange and a rear mounting flange; an inner link having a first end, a second end and an inner wire fixing part, the first end being pivotally coupled to the base member about a first inner link axis, and the inner wire fixing part being configured and arranged to guide an inner wire to be selectively guided in one of a top pull arrangement and a bottom pull arrangement; an outer link having a first end and a second end with the first end of the outer link being pivotally coupled to the base member between the front and rear mounting flanges to pivot about a first outer link axis; a chain guide pivotally coupled to the second end of the inner link about a second inner link axis and pivotally coupled to the second end of the outer link about a second outer link axis such that the chain guide is configured to move between a retracted position and an extended position relative to the base member; and a top/low adjustment mechanism coupled to the base member, the top/low adjustment mechanism including a top position adjusting bolt with a top longitudinal bolt axis arranged at an angle greater than zero degrees with respect to a longitudinal center plane of the bicycle frame and configured to selectively contact the inner link to selectively adjust the extended position of the chain guide with respect to the base member, and a low position adjusting bolt with a low longitudinal bolt axis arranged at an angle greater than zero degrees with respect to the longitudinal center plane of the bicycle frame and configured to selectively contact the inner link to selectively adjust the retracted position of the chain guide with respect to the base member, the rear mounting flange having the top and low position adjusting bolts of the top/low adjustment mechanism coupled thereto such that the top and low adjusting bolts are spaced longitudinally rearwardly from the first end of the outer link.
