My second frame build.

I've had a fatbike before, but I didn't like the traditional geometry and wide q-factor. So the main reasons for this frame was to have very similar geometry as my enduro bike, and a narrow q-factor crankset. Now I can swap between bikes and not have to adjust my riding so much.

I absolutely love the gearbox on the enduro bike, but I wanted to make at least one "normal" bike, just for reference 😊 I can live with the derailleur on a hardtail, and the fact that the winter trails are mostly very smooth...

Again, all the frame parts are selfmade, I even cut the threads on the BB with my manual lathe. Also the tools are selfmade, including tube bender. The dropouts and cable guides are the only bought parts for the frame itself.
