  • Patent number: 8075010
    Abstract: A bicycle including a front wheel, a rear wheel, and a frameset supported by the front wheel and the rear wheel. The rear wheel includes a first end cap and a second end cap, and each end cap has an aligned hole extending through the end cap. The rear wheel includes an axle that is positioned in the holes in the end caps and that defines an axial direction. The frameset includes a first dropout and a second dropout, each including an opening. The axle is positioned in the opening of each dropout. Each drop out has a lip that defines a slot aligned with and larger than the openings. Each of the lips is dimensioned to receive a corresponding end cap of the rear wheel. The lip of the first dropout has an axial length less than the lip of the second dropout.

  • Patent number: 8066297
    Abstract: A bicycle comprising a front triangle and a rear wheel having a rear wheel axis, a rear wheel suspension system further comprising a link further comprising a first pivotal axis for connection to said front triangle and a second pivotal axis for connection to a rear wheel swingarm, wherein the distance from said second pivotal axis to a first vertical plane decreases during a first portion of suspension compression and increases during a second portion of suspension compression; and wherein said first vertical plane is defined as a plane which is perpendicular to the ground and offset in the direction of the rear wheel with respect to the first and second pivotal axis. During the first portion of suspension compression and during the second portion of suspension compression the front triangle remains stationary with respect to the first vertical plane.

  • Patent number: 8033558
    Abstract: A bicycle rear suspension system includes a front part including a top tube, a down tube, a head tube and a seat tube. A rear part of the bicycle rear suspension system includes two seat stays and two chain stays. The seat stays have first ends pivotally connected to the dropouts on the first ends of the chain stays and two second ends pivotally connected to a first end of a connection member at a first pivot point. Two second ends of the chain stays are pivotally connected to a bridge between the down tube and the seat tube. A second end of the connection member is pivotally connected to the top tube. A cylinder has a first end pivotally connected to the bridge and a second end pivotally connected to a mediate portion of the connection member at a second pivot point.

  • Publication number: 20110181015
    Abstract: An aerodynamic braking system is disclosed herein. In particular, the brake arms may define an aerodynamic leading portion or edge and may be integrated into the legs of the front fork. Also, the brake arms may be disposed behind the bottom bracket shell to take the rear brake out of the air flow path and reduce aerodynamic drag. The rear brake arms are tapered so that the brake arms remain sufficient stiff to provide sufficient brake response times. The rear brake arms may be matched to recesses formed on an underside of chain stays.

  • Patent number: 7980579
    Abstract: This application relates to rear suspension system for bicycles, such as freeride, downhill and trail-style mountain bikes. The suspension system includes a rear suspension for coupling the rear wheel of the bicycle to the bicycle frame, a rear shock absorber disposed entirely in front of the seat tube of the frame and a linkage for operatively coupling the rear suspension to the rear shock absorber. The linkage intersects the longitudinal axis of the seat tube for transmitting rear suspension forces around the seat tube to the rear shock absorber. The seat tube is preferably continuous and is disposed so that the bicycle seat is adjustable over a full range of seat positions. The seat tube orientation ensures that the seat is movable between optimum biomechanical positions for both uphill pedaling and aggressive downhill freeriding.

  • Patent number: 7918474
    Abstract: A bicycle wheel dropout assembly that includes a split component axle mount assembly. An inboard and an outboard component of the axle mount assembly cooperate with overlapping portions of a respective seat stay and chain stay and are rotatably engaged therewith. An axle passes between adjacent mount assemblies and is offset with respect to an axis of rotation of the respective mount assemblies. The axle mount assemblies secure the overlapping portions of the seat stay and the chain stay relative to one another and support the axle in a manner that is convenient for drive train maintenance and/or servicing.
