Abstract: A damper assembly for a bicycle wheel assembly may include a first damper configured to be disposed about a hub assembly of the bicycle wheel assembly. The first damper is configured to apply a damping force against a spoke segment of at least one spoke of a plurality of spokes of the bicycle wheel assembly. The first damper includes a first end applying the damping force against the spoke segment.

Abstract: A bicycle wheel assembly may include a rim, a hub assembly, a plurality of spokes and a damper assembly. The damper assembly includes a damping element configured to apply a damping force against at least one spoke of the plurality of spokes. The damping force may be applied in an axial direction of the bicycle wheel and/or to a segment of the at least one spoke near the hub assembly.

Abstract: A master cylinder assembly for a hydraulic actuation system for a handlebar-steered vehicle. The master cylinder assembly generally includes a housing mountable to a frame member of the handlebar-steered vehicle and having a chamber including a fluid cavity with first and second fluid cavity regions. The first fluid cavity region is in fluid communication with the hydraulic actuation system. The housing includes discrete first and second housing portions. The first housing portion has first and second end portions. The first end portion of the first housing portion extends axially into the second fluid cavity region creating an annular gap radially outboard of the first end portion extending into the second fluid cavity region. The second end portion of the first housing portion is connected to the hydraulic actuation system. A piston assembly includes a piston slidably disposed within the fluid cavity.

Abstract: A brake actuation assembly for a hydraulic brake system of a handlebar-steered vehicle, the brake actuation assembly including a housing mountable to a handlebar of the vehicle and having a chamber formed therein. A piston assembly is received and axially guided within the chamber. A linkage is pivotally attached to the housing and the piston assembly and a lever blade is connected to the linkage to effect movement of the linkage, wherein movement of the linkage produces a variable rate of travel of the piston assembly relative to the travel of the lever blade.

Abstract: A master cylinder assembly for a hydraulic actuation system for a handlebar-steered vehicle including a fluid cavity having an adjustable length. The master cylinder assembly generally includes a housing, a piston assembly, an actuator and an adjuster. The housing is mountable to a frame member and includes a chamber having a fluid cavity with first and second regions. The first region is in fluid communication with the hydraulic actuation system. The piston assembly includes a piston slidably disposed within the fluid cavity. The actuator is operatively connected to the housing and operatively connected to the piston to slidably displace the piston between an open fluid circuit position permitting fluid flow between the first and second regions and a closed fluid circuit position blocking fluid flow between the first and second regions. The adjuster is operatively connected to the housing to adjust a length of the fluid cavity.

The first region is in fluid communication with the hydraulic actuation system. A piston is slidably disposed in the fluid cavity. An actuator is operatively connected to the housing and operatively connected to the piston to slidably displace the piston between an open fluid circuit position and a closed fluid circuit position. A first seal is disposed on either the piston or a wall of the fluid cavity. The first seal is configured to be in sealing engagement between the fluid cavity and the piston with the piston in the closed fluid circuit position to block fluid flow between the first and second fluid cavity regions.
