Soma Fog Cutter Frame


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.
