XTR:一种越野车零件的艺术代表
XT:对高性能山地车套件技术的不懈追求
LX:居家、户外汽车的高能量套件
Deore:带来真正骑车乐趣的高性能套件
我大概以2003年的牙盘+中轴为例来说说区别吧:当然了,Deore以上都是中空曲柄臂加花键(Deore有一款是方孔)加9速的,下面主要说区别。
XTR:曲柄臂是铸造硬质铝,盘片都是7075铝的,链轮螺母螺钉也都是7075铝的,腿的长度从165~180mm,每2.5mm有一个型号,也就是说有7种长度,平均重量797克中轴和牙盘是一体的。其他几个型号都不是一体的。
XT:曲柄臂是铸铝,中盘小盘片不是7075铝了,螺母和螺钉也是普通铝,腿的长度一共有5种规格,平均重量872克。
LX:在XT的基础上,大盘中盘是铝的,小盘片是钢的,螺钉为不锈钢,螺母为钢,腿的长度只有170和175mm两种规格,平均重量906克。
Deore:中盘小盘都是钢的,大盘有一种钢的一种铝的,中轴有一个型号不是中空的(un),另一个型号(es)是和LX以上类型一样是中空的,平均重量为972克~1093克。
再举例说说飞轮:都是9段的
XTR:大的四片盘片是钛的,小的五个是钢的,齿片表面处理是镀层材料为Ti/Ni-P轻质合金底座,重量240克
XT:从XT往下全部为钢盘片了,齿片表面镀铬,重量300克
LX:底座不再是轻质合金,齿片表面处理为"珠光表面处理",重量330克
Deore:齿片表面处理为镀Ni,重量358克
看了上面的,大家应该有点体会了。XTR就是不惜成本的要把东西做成精品,其实并不见得不耐用的,但是有时候在高性能和耐用上会一定程度上考虑前者。
XT是去掉了奢侈品的好代表:例如不用钛片什么的,不用特殊材料,都还是用价格比较合理的材料。LX为简略版XT,个别地方就开始偷懒。Deore则够用就行的了。
