Critical Mass is a group bicycle ride which takes place at regular intervals (usually on a monthly basis) whose purpose is to "celebrate cycling and to assert cyclists' right to the road." Although it is a nationwide movement, there is no centralized organizational structure, and there are no official leaders. The CM group in Rochester has been in existence since 1998.

The [WWW]CM website describes the concept thusly:


Critical Mass originated in San Francisco in September of 1992. It spread to Rochester in 1998 when University of Rochester graduate student Mark Anderson began organizing rides originating in River Campus. Rides grew to about 50 cyclists by summer 1999, but many first-time riders expressed dissatisfaction and felt turned off by illegal riding and the hostility toward cars and never returned. By winter 2001 the rides had fallen apart, and occasional riders would send mail asking where everyone was. Mark finished his doctorate in May 2002 and departed to teach in Geneva NY.

Tobin Fricke arrived fall 2004 as a graduate student in physics, and shortly with Robert Polyn and others co-founded RocWiki and Ant Hill Cooperative, and along with Andrew Hall of Cooperative EcoHouse revived Critical Mass in Rochester. He penned [WWW]this contemporaneous post.

To plan critical mass rides in Rochester or to find out when the next ride is happening, sign up for the [WWW]Rochester Critical Mass mailing list or send an e-mail to []. Critical mass rides occur on the last Friday of the month. The ride departs from the Wilson Commons clocktower on the UR campus at 5:30pm and from the Liberty Pole (downtown) at 6:00pm, as agreed on the April 2006 ride. There have been rumors of making the ride once a week, rather than once a month, as Rochester has weekly rides three other nights of the week.
