ABSTRACT:
Bicycle derailleur mounting apparatus for use with a suspension bicycle including a front triangle and a rear triangle coupled to allow limited relative pivotal movement or travel therebetween during operation. The apparatus includes a derailleur link having a derailleur mounted thereon. Mounting structure mounts the derailleur link relative to one of the front triangle and the rear triangle to move independently of the front triangle and the rear triangle during travel. The independent movement is driven as a function of travel position of the front triangle and the rear triangle. The mounting structure is designed to position the derailleur to maintain shifting performance, to maintain chain retention, and to maintain good front derailleur to chainstay clearance, at desired points along the travel.
