Look, I'm not suggesting anyone actually tries a 12-player game of this ... I am merely pointing out that there are now 12 different sets of colours available for the cyclists.
The standard set has Black, White, Blue, Red, Yellow and Green.
The extra colours are:
The brown and the gold are a little bit similar in colour in poor lighting.
