New Belgium Brewing's Tour de Fat returns to Boston for a second-straight year, this time with musical act The Voidz headlining the festivities. A celebration of all things bikes and beer, this event features musicians, circus performers, vaudeville acts, magicians, comedians and games. Best of all, proceeds go directly to the Bike Union, so you'll be supporting our mission while reveling with your friends and fellow cyclists. There's fun for the whole family, and everyone 21+ can enjoy year-round beers…
