A bicycle fluted disc is provided with a chain wheel body, a chain ring, a plurality of limiting pieces and a plurality of reinforcing pieces. The chain ring is provided with a plurality of chain tooth pieces, and each chain tooth piece comprises a plurality of chain teeth. Through movement of the chain ring relative to the chain wheel body, the limiting piece limits the amplitude of axial movement of the chain ring and the reinforcing piece stabilizes the connecting strength between every two adjacent chain tooth pieces. When the bicycle fluted disc drives the chain, the chain ring can move relative to the chain wheel body so as to reduce friction and noise between the chain teeth of the chain tooth pieces and the chain.
一种自行车齿盘,具有一链轮本体、一链环、多个限位件、多个补强件。其中,该链环具有多个链齿件,且各该链齿件包含有多个链齿。通过该链环相对该链轮本体的移动、该限位件限制该链环可轴向移动的幅度以及该补强件稳固两个相邻的该链齿件之间的连结强度,当该自行车齿盘带动该链条时,该链环可相对该链轮本体移动以减少各该链齿件的该些链齿与链条的磨擦与噪音。
