  • Patent number: 9487199
    Abstract: A hydraulic brake mechanism is described including a housing. A master cylinder assembly is disposed within the housing, and the master cylinder assembly includes a fluid chamber. The fluid chamber includes a first chamber portion having a first diameter and a second chamber portion having a second diameter, with the first diameter greater than the second diameter. The fluid chamber includes a transition region between the first and second chamber portions. The mechanism includes a piston assembly having a piston disposed within the fluid chamber. A first seal is configured to sealingly engage between the first chamber portion and the piston, and a second seal is configured to sealingly engage between the second chamber portion and the piston. The mechanism includes an outlet port extending from the fluid chamber from or adjacent the transition region.

  • Patent number: 8162343
    Abstract: A mounting device is shown for mounting components to a bicycle handlebar having a handlebar axis. The mounting device includes a mounting bracket mountable to the handlebar about the handlebar axis. The mounting bracket includes a first clamp portion and a second clamp portion hingedly connected to the first clamp portion to interiorly receive the handlebar. An interior channel is defined by spaced sidewalls and formed in a portion of the circumferential length of one of the first and second clamp portions, and a hole is formed through the clamp portion and opens to the channel.

  • Patent number: 8061667
    Abstract: A mounting device for mounting first and second bicycle control components to a bicycle handlebar having a handlebar axis. The mounting device generally includes first and second mounting brackets. The first mounting bracket is adjustably mounted to the handlebar about the handlebar axis. One of the first and second bicycle control components is attached to the first mounting bracket. The second mounting bracket is adjustably attached to the first mounting bracket. The other of the first and second bicycle control components is attached to the second mounting bracket. The second mounting bracket is displaced between alternative attachment positions on the first mounting bracket. The first mounting bracket is rotated between alternative mounting positions on the handlebar.
