Set of 4 reflective cyclo-reflectors for a bicycle. By using it, visibility can be increased in adverse weather conditions and in the dark. The set consists of a front white reflector, a rear red reflector and two pieces of orange reflectors suitable for placing in the wheel string. The standard attachment of individual elements facilitates their placement. The front and rear reflectors can be adjusted to the desired angle using a screwdriver. The front reflector is suitable for a pipe with a maximum diameter of 22.2 mm, the rear reflector is suitable for a pipe with a maximum diameter of 27.2 mm. The orange reflectors are simply put on and "stuck" with the grooves in the wheel string.
