Patent number: 11787496Abstract: A bicycle includes a frame, a suspension assembly and a steering assembly. The frame includes a head tube that rotatably receives a front fork assembly. A steerer tube extends axially away from a fork crown of the front fork assembly. The suspension assembly includes an upper tubular support longitudinally slidable relative to a lower tubular support. The upper and lower supports receive a first positive biasing means and a first negative biasing means. The lower and upper supports are respectively connected to the steerer tube and a stem of the steering assembly such that the upper support slides longitudinally relative to the lower support adjacent the stem and above the fork crown.Type: GrantFiled: November 25, 2020Date of Patent: October 17, 2023Assignee: Specialized Bicycle Components, Inc.Inventors: Christopher P. D'Aluisio, Jean-Luc Callahan, Tyler Kraus, Conner Swarthout, Michael McAndrews

Patent number: 8857843Abstract: A bicycle including a main frame, a front wheel mounted for rotation relative to the main frame. a rear dropout, and a rear wheel mounted for rotation relative to the rear dropout about an axis. The rear wheel defines a center plane of the bicycle and is driven by a chain. The bicycle also includes a seat stay coupling the rear dropout to the main frame. The seat stay has an inner surface facing the rear wheel and an outer surface facing away from the rear wheel. The seat stay includes a steep portion having an outer surface disposed at a steep angle of between about 25 degrees and about 75 degrees relative to the center plane, and at least a portion of the steep portion is disposed outboard of the chain.Type: GrantFiled: July 30, 2013Date of Patent: October 14, 2014Assignee: Specialized Bicycle Components, Inc.Inventors: Jean-Luc Callahan, Christopher D'Aluisio
