    摘要： A bicycle gear changing control apparatus includes a controller that is programmed to control a gear changing state of a bicycle transmission according to an operation of a gear changing operating device upon determining a bicycle traveling speed is greater than a first speed. The controller controls the transmission automatically to be in a first prescribed gear changing state upon determining the bicycle traveling speed becomes less than or equal to the first speed and upon determining a gear ratio of a current gear changing state of the transmission is larger than a preset gear ratio of the first prescribed gear changing state. The controller controls the transmission automatically, after controlling the transmission to be in the first prescribed gear changing state, to a larger gear ratio than the gear ratio of the first prescribed gear changing state, upon determining the bicycle traveling speed becomes greater than a second speed.

    摘要翻译： 一种自行车换档控制装置，包括控制器，其被编程为在确定自行车行驶速度大于第一速度时根据变速操作装置的操作来控制自行车变速器的档位改变状态。 在确定自行车行驶速度变得小于或等于第一速度时，并且当确定变速器的当前变速状态的变速比大于预设时，控制器自动地将变速器控制在处于第一规定档位变化状态 第一规定档位变化状态的齿轮比。 在确定自行车行驶速度变得大于第二速度之后，控制器在将变速器控制在第一规定档位改变状态之后自动控制变速比比第一规定档位变化状态的档位比大的变速比 。

    摘要： A bicycle rear sprocket assembly comprises a plurality of sprocket members and a supporting member. The plurality of sprocket members have a rotational center axis. The plurality of sprocket members are arranged in an axial direction parallel to the rotational center axis. The plurality of sprocket members each include a sprocket body and a plurality of sprocket teeth. The plurality of sprocket teeth extend radially outwardly from the sprocket body with respect to the rotational center axis. The supporting member is a separate member from the plurality of sprocket members. The supporting member includes a supporting portion and a hub engagement portion. The supporting portion is configured to support the plurality of sprocket members. The sprocket body of each of the plurality of sprocket members is attached to the supporting portion of the supporting member without using a separate metallic fastening member.

    摘要： A bicycle bottom bracket assembly having a rotational central axis includes a support member, a bearing unit and a radially inward force reducing structure. The support member includes a hanger mounting portion and a bearing mounting portion. The bearing mounting portion is configured to be at least partly positioned within a hanger part of a bicycle frame. The bearing unit includes an outer race, an inner race and at least one roller element disposed between the outer and inner races in a radial direction with respect to the rotational central axis. The outer race is fixed to the bearing mounting portion of the support member. The radially inward force reducing structure reduces a radially inward force being transmitted to the bearing unit.
