Soma Fabrications Fogcutter Frameset

About Soma Fabrications:

Practical, durable, comfortable, affordable… these are the primary forces shaping Soma’s ideology. Sounds reasonable right? But why do so many other companies try to emulate the racing world when it’s the smallest segment of the market? Our local bike shops have felt a lack of ‘real’ products aimed at the everyday cyclist and occasionally pitch their ideas at us. The results: A better tire lever, water bottles that don’t taste like plastic, and steel frames that’s got people smiling from the commute to the singletrack. The San Francisco Bay Area is where we are located. We love the year round riding weather here and the strong bike culture. It’s a great place to live and cultivate new ideas.

The Fog Cutter is an endurance road/road sport design. We designed it to fit fatter tires, but the frame angles are more road bike than CX or gravel bike. It can float you over chewed up asphalt better than most bikes in this category. This is the frame you want for long days in the saddle and the most demanding commutes.

  • What kind of forks are compatible with the Fog Cutter?

    Even though we call this a road bike, we built the frame around a cyclo-cross length fork. So anything 390-400mm in length with a 44mm rake will work as designed. (48/50mm rake for the 48 and 52cm size) We do make a robust matching straight blade carbon fork for this frame, but you can run our lugged CX Disc Fork or Straight Blade CX fork. Or a third party CX fork. It needs to have a 1-1/8″ steerer though. Road forks will be too short for this frame.
