Critical Mass out the Ass

Celebrating 20 Years of turning the right of way into so much more.

Damn, these Levi’s commuter jeans are strangling my junk.

Critical Mizzle, Bizzle! Get out there and cork it up for the cause, yo.

Over a Million Motherfuckers!

“We’ve seen a million faces, and rocked them all.”

Congrats to everyone who took advantage of the 48-hour FREE song and ringtone offer to celebrate the million-view milestone.

If you missed it, you can still get them for 75¢ (or as much as you’d like to donate) at sonsofscience.bandcamp.com

Thanks for sharing the MFB love - now go buy a motherfucking sticker.

Critical Mass today bitches! Get out there and piss off some motorists while spreading awareness and promoting a cycling-friendly agenda.
