自行车轮胎尺寸

26*1.75 表示车胎的直径为26英寸,宽度为1.75英寸。这种车胎为山地车胎或现代的民用车,采用的是标准的英制车圈。
26*1又3/8,28*1又1/2表示车胎直径为26英寸 28英寸,宽度为1又3/8英寸,1又1/2英寸。这种车胎为老式民用车采用像传统的凤凰永久飞鸽,以前生产的车圈,由于国内的制造规范与国外不统一,所以尺寸比标准的英制略大。

SHIMANO套件

SHIMANO的自行车部门主要生产自行车的变速,传动,刹车等配件,我们一般统称为套件,具体包括:前拨链器(前拨),后拨链器(后拨),变速手柄(山地有转把、指拨、双控手柄这几种形式,公路有手变(STI双控手柄)和指拨),前链轮(牙盘),后链轮(飞轮),链条,花鼓,刹车,以及相关的各种变速线、管,刹车线、管、油等等配件。

SHIMANO各等级套件的名称

运动级别的山地越野用套件,从高到低的名称依次是:XTR、Deore XT、Deore LX、Deore、ALIVIO、Acera、ALTUS、TOURNEY,更低的C050,SIS之类民用变速不在此列,另外还有HONE(介于XT和LX之间,适用重型XC和AM)、SAINT(介于XTR和XT之间,适用于AM和FR)、适用于小轮车的DXR,capreo用的较少,也暂不探讨。
运动级别公路用套件,从高到低的名称依次是:DURA-ACE、Ultegra、105、TIAGRA、SORA、2200,更低的用于民用的A050和SIS都不在此列。

山地越野:XTR是竞赛级、Deore XT是训练级、Deore LX是专业训练级、Deore是专业入门级、ALIVIO是娱乐级、Acera和ALTUS都是娱乐级、TOURNEY算是入门娱乐级。Deore是个分水岭,Deore(含)以上都可以称为专业级。
公路:DURA-ACE是竞赛级、Ultegra称为专业训练级、105是专业入门级、TIAGRA是业余级别、SORA是娱乐级、2200算是入门娱乐级。这其中105是个分水岭,105(含)以上都可称之为专业级。
以上的级别分法是比较含糊的,所谓娱乐就是特指非代步的骑行运动。
