MAVIC自诩open pro是公路竞赛的“参考级”车圈，此等描述相当具有煽动性，而在OPEN PRO系列中，又有一款非常特殊的CD涂层款式，大致就是在铝合金表面做了硬化处理，使得更耐用。
单单从外观来说，灰色的车圈至少我是头一次看见，不知道骑出去的回头率高不高
原文如下
CD
Concept :
This type of adonization process reinforces the oxide layer that forms on the aluminum profile surface.
On the surface of the rim, a greater micro-hardness is obtained.
Benefits :
- Greater resistance to wear (150 - 400 times higher than any other type of adonization).
- Greater resistance to corrosion.
- Easier to build and balance the wheel.
