MASH SF is a group of riders, messengers, designers and photographers born some years ago among the fixed gear fans of the West coast. Their short film MASH made them cult-famous around the world. MASH Bolt frameset marks the return of the original Bolt geometry preferred by long distance riders and racers for its more comfortable approach.
