Lovely bike Marius. The SK with 24” wheels handles fenders nicely. I opted to squeeze 26” wide rims and tires and forego the fenders.
Here’s the front with no truss rods. The tire interferes with truss bracket.
Rear wheel needs the axle most of the way back.
I really wanted the truss, so I welded the inner parts of the fork dropouts to lower the front axle.
Good luck with your project. You’re gonna love this bike.
