We made a small (but important) error on the original poster.  It said show time was 3pm to 7pm.  It's actually 1pm to 7pm.  Here's the new one....
Date: March 20 2011 
Location: Una Pizza Napoletana 210 11th St and Howard St. San Francisco, CA 94103
The  greater San Francisco Bay area is home to numerous world-renowned  bicycle frame builders.  On March 20th many of them will converge at Una  Pizza Napoletana in San Francisco for 'A Ruota Libera', a bicycle and  pizza show designed to showcase and celebrate the rich culture and  history of frame building that exists right here in our own backyard.
Anthony  Mangieri, owner and pizzaiolo of Una Pizza Napoletana, is an avid  mountain biker and owner of several custom made bicycles. For Mangieri,  the event represents an opportunity to invite fellow craftsmen, who  share his appreciation for detail, into his own 'workshop' where he will  happily churn out his signature Neapolitan pizzas for the show.  
Sean  Walling, owner and frame builder behind Soulcraft Cycles, immediately  saw the value of bringing local builders together for the show and  partnered with Mangieri to bring A Ruota Libera to life.  "The frame  building talent we have within a 50 mile radius is an embarrassment of  riches," says Walling, “and Anthony has the same obsessive approach to  pizza that we have to bikes, so why not get together and give the locals  the opportunity to experience this all in one place."
Walling  and Mangieri both agree that A Ruota Libera will be a great venue for  all, whether frame builder or fan, to appreciate what results from years  working toward mastering a craft.
A Ruota Libera will also  showcase a live musical performance by the internationally praised duo,  The Mattson 2 and a screening of 'FROM STEEL': The Making of a  Soulcraft' by director Michael John Evans.  
The name “A Ruota Libera” is Italian for “Freewheel.”
Moretti Beer and Mr. Espresso coffee will also be available.
Admission to the event is $10 (includes pizza)
Free on site bike parking will be provided.   
Tickets are available at the door the day of the show.  
Doors open at 1pm and close at 7pm.
