Almost by chance, I came across the "3M" spoke reflectors on the Internet and was immediately enthusiastic about the idea. With Amazon Mondays Thursdays ordered delivered.
The package contains 75 sticks that are clipped onto the spokes. Sounds simple, but it takes a good half hour but already when the rods still aligns something. The resistance to the rods aufzuclipsen on the spokes was slightly increased, but I hope that by not easily adopt this with bumps.
About 2 dozen sticks are left, for just in case. Everything is street legal (with some chopsticks is a test no. Printed).
Hopefully these rods help that car and cyclists in future
rarely get in the hair. The product is definitely worth the money!
