The Soma Fog Cutter Frameset is ready for long days in the country or aggressive rides through the city. The double-butted steel frame is designed to handle wider 700c or 650b tires, but it retains a road sport geometry that makes it more nimble than a cyclocross or gravel bike. Fender mounts, rear rack mounts, and disc brake tabs are all there, allowing the Fog Cutter to be equipped for almost any purpose.

Claimed weight is 4.5 lbs (size 58 mm).


  • Tange Prestige heat-treated double butted CrMo steel tubing
  • Carbon fork with alloy steerer
  • Road sport geometry
  • Rear rack & fender mounts
  • International disc mounts (rear mount is located on the chainstay for stiffer performance and also keeps the caliper out of the way of rear racks)
  • 1-1/8" headtube
  • 27.2 mm post size
  • Compatible with bottom-pull front derailleurs with 28.6 mm clamps
  • Designed for 160 mm rotors
  • Fits 700c and 650b wheels. Max tire size is 700c x 38 mm with fenders
  • 68 mm, English-threaded bottom bracket

Great frame for my NYC commuter build - fairly stiff front end with good power transfer, but sails over rough pavement comfortably. Very happy to have gone for it!

Classic Steel Meets Modern Brake and Tire Functionality

I bought TWO of these framesets on sale to build up and send to Peru as donations. They are perfect for the almost 100% gravel riding they will be subject to. Check it out httpsg2strategic.wixsite.comequipocasagirasoles

The Soma Fog Cuttter is a WONDERFUL riding bike! I've been on carbon so long I had forgotten how truly nice steel is. Add some chubby gravel tires and you are ready for one mellow ride. Gorgeous paint, fender and rack dropouts galore. Just wish it was TA instead of QR.

Best fitting bike I've ever had.

Stiff, reliable steel, fast geo, and large tire clearance

The fog cutter is a fast road gravel machine

I love this bike. It's well designed and much lighter than similar CrMo steel frames from brands like Surly or All-City. I bought it because I was looking for a bike that could function well as a fast commuter, winter road trainerrain bike, and gravel adventure bike.

Pros the ride is fun and pretty snappy (not upright and sluggish like some other all-roadadventure frames), you can hang in the paceline and also ride trails and gravel roads confidently on the same bike, fender mounts on frame fork (the carbon fork has recess for fork crown daruma), tire clearance -

fits fenders with 700c x 33s and 650b x 47, disc brakes make swapping wheel sizes really easy, the paint scheme is sharp.

Cons no frame pump peg, paint chips easily, carbon fork is relatively heavy due to aluminum steerer
