Abstract: The present disclosure relates to a chain ring having teeth positioned in one of three lateral positions. At least one tooth may be placed in each lateral position. At least half the teeth may be positioned in a middle lateral position. The teeth in the first and third lateral positions may apply opposing lateral forces to a bicycle drive chain.

Abstract: A guard for a chain and chain ring of a bicycle includes a bracket and a bracket extension. The bracket extension has a first end and a second end, and at least the second end is integrally formed. The second end includes a U-shaped configuration configured to house a chain retainer. The bracket and the bracket extension may be secured to one another using two fasteners. The bracket and the bracket extension may rotate relative to one another when only one of the fasteners is attached and may be fixed relative to one another when both of the fasteners are attached.

Abstract: A control apparatus for controlling one or more functions of a controlled device includes a movement sensor operable to detect both a direction of movement and an amount of movement of the control apparatus, a microcontroller for receiving a signal corresponding to the direction and amount of movement and generating one or more corresponding control signals for controlling the controlled device, and a transmitter for transmitting the control signals to the controlled device. The control apparatus may include a position selectable control and a sensor coupled to the control to sense a position thereof. According to some implementations, the movement sensor may be used to control a direction of the controlled device, and the position selectable control may be used to control a speed of the controlled device.
