As per smell_it, my sks came with some plastic spacers and longer bolts, so the secuclip thingy was just spaced out away from the disc caliper. No bending required, looks tidy, and fitted in half hour and solid ever since. I thought the chromoplastics had the same fitting as the bluemels, well my last set did. The spacers probably do knock the front flap a mm or so off, but not enough to vex my ocd traits.
The chromoplastics do have longer coverage, but I was tight and my feet are fine; my overshoes take care of any splash, and the rain which tends to fall from the sky around my way. I don’t ride in groups so I’m not fussed who is behind me.
