Abstract: A bicycle rim brake comprises a first shaft, a second shaft, a first brake arm, a second brake arm, and a reinforcing member. The first shaft includes a first fixed end part fixedly provided with respect to a bicycle body. The second shaft includes a second fixed end part fixedly provided with respect to the bicycle body. The first brake arm is pivotally provided on the first shaft around a first pivot axis. The first brake arm has an opposite surface opposite to the first fixed end part. The second brake arm is pivotally provided on the second shaft around a second pivot axis. The reinforcing member couples the first shaft to the second shaft. The reinforcing member is provided such that the first brake arm is at least partially arranged farther from the first fixed end part than the reinforcing member.

Abstract: A bicycle brake arm basically has a first branch and a second branch. The first branch includes a cable attachment structure. The second branch extends from the first branch. The second branch includes a brake shoe attachment structure. At least one of the first and second branches includes an interior cavity. The at least one of the first and second branches has a transverse cross-section in which the interior cavity is completely and continuously surrounded by an exterior surface of the bicycle brake arm.

Abstract: An apparatus for supplying fluid of preset quantity comprises a fluid supplying pump provided in a fluid supplying pipe arrangement, a motor for driving the fluid supplying pump, meter for metering the fluid flowing in the fluid supplying pipe arrangement, and a control circuit for detecting that supplied quantity of fluid measured by the meter has reached a quantity smaller than a preset fluid supplying quantity by an estimated oversupply quantity of fluid, and stopping the motor from being driven. The estimated oversupply quantity of fluid is set to a quantity equal to a quantity of fluid supplied by the fluid supplying pump after the motor is stopped from being driven and rotates due to inertia.
