In Rome, at the end of May, for the seventh consecutive year thousands cyclists from the all world will meet for riding together. From the 28th to 30th of May the Critical Mass will be “Interplanetaria” (interplanetary), the “Ciemmona” (big CM).

The city will be invaded from the colors, the sounds and the door-bells of the more joyful and critical event of the city cyclists of all the world.

The Ciemmona was born from the idea of some participants of Roman CM (Critical Mass) to share this moment of joy and knowledge, with the cyclists of the other Italian and international Critical Mass. Starting the first time in Rome at 2004, this event has grown till to count beyond 6 thousand cyclists.

All disposed ones to resume the road and to demonstrate that the car in city is by now an obsolete means.

Also this year the appointment is to Rome, at the end of May, for CIEMMONA 2010.
