There is no right or wrong here, especially with Soma's frames since they dont even come with forks and you can order forks with different rakes from them. As long as you get a fork with the correct A-C length, buy the rake that you want to get the trail that you want. A 43mm rake fork, 45mm rake fork, or 50mm rake fork will all work just fine- its really a matter of how do you want the handling to feel.

-- If you want to choose a third party option, please look something with the following specs. 1-1/8" non-tapered steerer, 390-400mm axle to crown length, and of course something that will fit the bike hub on your front wheel. 48mm rake is ideal. 44mm rake is acceptable. Please follow their instructions carefully.

What kind of forks are compatible with the Fog CutterEven 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.
