A hydraulic assembly for a hydraulic disc brake system that includes a housing defining a cylinder, a piston received in and moveable within the cylinder, a first lever operatively associated with one of the piston or the cylinder, and a second lever operatively associated with the other of the piston or the cylinder. Moving the first lever pushes one of the piston or the cylinder in a first direction, and moving the second lever pulls the other of the cylinder or the piston in a second direction. In a preferred embodiment, the piston has a non-actuated position and a fully actuated position, and the piston is biased towards the non-actuated position, and wherein the cylinder has a non-actuated and a fully-actuated position, and the cylinder is biased towards the non-actuated position.

A display device for a bicycle includes a memory for storing a plurality of tire circumference values and a plurality of tire designation values; display means for displaying information, wherein the display means includes tire designation display means for displaying tire designation information corresponding to the plurality of tire designation values; control means for controlling the information displayed on the display means; and input means for inputting commands to the control means. The display means may include tire circumference display means for displaying tire circumference information corresponding to the plurality of tire circumference values simultaneously with the tire designation information displayed by the tire designation display means. The display may further include correction storing means for storing a plurality of correction values and correction display means for displaying a plurality of correction information corresponding to the plurality of correction values. In this case the control means includes means for selecting one of the plurality of the correction information displayed by the display means so that the correction information may be used to adjust the value of a selected tire circumference.

A device for transmitting sensor signals in a bicycle includes a sensor for sensing an operational condition of a bicycle component and for outputting a sensor signal having a selected type. A digital transmission circuit operationally associated with the sensor outputs a digital message in response to the sensor signal. The digital message includes 1) a digital sensor value comprising a series of bits representing a value of the sensor signal; and 2) a digital identification value for indicating the selected type of the sensor signal. Such a message allows a sensor having any physical design to be connected to the computer.
