Win a Marin Alcatraz Dirt Jump Bike @ the SF Bike Expo, worth $1199.99. Half of the proceeds go to the SF Urban Riders Mclaren Park Bicycle Park and the other half will go towards putting on AT’s Showdown.

Come out this Friday to buy raffle tickets, eat pizza, drink beer, and meet the Marin Dirt Jump team. We’ll all be at the brand new Marin Bikes Outlet Store, located at 1090 Folsom St at the corner of 7th St.

If you can’t make it, $10 raffle tickets can be purchased online, at the rideSFO store (1724 Mandela Parkway Suite #2 Oakland, CA 94608), or at the Expo. Winners will be notified by phone or email.
