San Marcos Frame Set

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.

  • Clydesdale's take on his 63cm San Marcos

    “I like it. I have not ridden as much as I would have liked because I have been on the "fast" bike but I have taken it out for a few 40K + rides and many smaller ones. Very comfortable with lots of spring due to the tubing size but not a lot of flex - so get the benefits of comfort of small tubed steel without noodliness (sic). I'm a clyde and it is very appropriate for all-rounder - better for my actual application than a cross bike. The bike is everything I hoped my Cross-Check would be (and was not). Nimble, fast, light, and versatile. ”
