Question about knog. Blinder 1300

Basically, yes. However, there are different types of aerobars, so it should be noted that the blinder can be attached to a 'tube' that is at 90° to the direction of travel and should be horizontal for the sake of appearance. Personally, I also recommend the fixed bracket, but that's my personal opinion.

It can be attached to any steering wheel and holds well!

No, rather not! The brackets are made for "round" bars.
