Soma San Marcos Frame
The San Marcos is a "sport touring" road frame designed by Grant Petersen of Rivendell. It is a fine ride on black top and smooth fire roads. While not designed for loaded touring, it can probably handle that type of duty even better than the Double Cross, which was Soma's go-to choice for touring before the Saga was designed. New features for 2014 include mini rack braze-ons on the fork.
