A bicycle sprocket arrangement comprises a largest sprocket, a smallest sprocket, and a plurality of intermediate sprockets. A first quotient is obtained if a total tooth-space number of the large sprocket is divided by a half of the tooth-space number difference. The first quotient is an even number with respect to all sprockets of the plurality of intermediate sprockets. A second quotient is obtained if the total tooth-space number of the small sprocket is divided by a half of the tooth-space number difference. The second quotient is an even number with respect to all sprockets of the plurality of intermediate sprockets excluding a largest intermediate sprocket of the plurality of intermediate sprockets.
一种自行车链轮组件,包括最大的链轮、最小的链轮和多个中间链轮。如果大链轮的总齿槽数除以齿槽数差的一半则得到第一商。第一商相对于多个中间链轮中的所有链轮是偶数。如果小链轮的总齿槽数除以齿槽数差的一半则得到第二商。第二商相对于除多个中间链轮中的最大的中间链轮之外的多个中间链轮中的所有链轮是偶数。
