If you train in the dark, you should be as visible as possible. A clever solution: round plastic clips coated with Scotchlite reflective material that are attached to the spokes. Microscopically small glass particles reflect incident light, which blurs into a brightly glowing surface in the rotating wheel. According to the StVZO, the eight-centimetre-long clips may be fitted instead of "cat's eyes" if all spokes in both wheels are fitted with them. They only fit on round spokes with a diameter of 1.8 and 2 millimetres and are available under the brand names "3M" (content: 75 clips) and "Büchel" (72 clips).
Price: 20 Euro

PLUS: Highly visible; do not get dirty as quickly as reflective strips on tyres
