What Color would you like your Mountain Bicycle Hubs to be?

We just released our second generation of Rollingstar MTB hubs. The current available colors for these hubs are black and silver. >> Rollingstar II MTB

We are also planning to make several other colors. We would like to hear your suggestions. Would you leave a comment below the article about your color preference? The available colors are shown in the picture below. Thank you very much!
