theres aluminum strips in SKS mudguards, glad those work , l use a wiring lead .
tape and zip ties rather than the strips in the mudguards

I see the coil of wire , I dont understand why it wouldn't go with another rack with the same

euro 2 hole 5~6cm spaced hole mounts..

Even the Trek-Bontrager ones we get stateside, have that mount set up.
they are kinda like the ones in your lower of the 2 first post .. pictures.
