据我知道:红圈有28孔的,仿佛是定制的版本
另,红圈稍轻了些克数。
其他都一样。
8R20 8R31
补充
Nexus 8
Nexus 8 Premium
It is 200 grams (nearly 1/2 pound) lighter than the Standard Nexus Inter-8, and is easily distinguished from the standard 8-speed by a RED BAND on the drive side of the hub barrel.
指RED BAND的红线版本比标准内八轻了200克(我表示怀疑)
它们的速比是一样的
