Abstract: A bicycle seat post isolator assembly constructed to be fixedly engaged in a seat post receiving opening in a bicycle frame. A seat post gripper includes an elongated inner tubular body with an outer elastomeric layer/covering, inserted into the opening to receive a seat post coaxially therein. The layer/covering is positioned between the body and the bicycle frame. A retaining structure designed to be fixed adjacent an edge of the seat post receiving opening with a portion extending into the opening to only engage portions of the outer elastomeric layer/covering of the seat post gripper so as to lock the seat post gripper in the seat post receiving opening, whereby the layer/covering of the gripper is positioned between the body of the gripper with the seat post inserted coaxially into the gripper and the bicycle frame.

Abstract: A bicycle frame with removable dropouts includes a bicycle frame having a left seat stay and a left chain stay joined at a left junction, and a right seat stay and a right chain stay joined at a right junction. A left dropout is removably connected to the bicycle frame at the left junction, the left dropout including a body defining an opening for receiving a rear wheel. A right dropout is removably connected to the bicycle frame at the right junction, the right dropout including a body defining an opening for receiving the rear wheel.

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.
