Simple and inexpensive do-it-yourself modification, with amazing results. This truly is an absolute must-have for any anything with wheels if you want to add safety to your ride, and to stand out! They reflect light back at the light source that shines on them (like incoming headlights), giving the glowing effect. Unique triangle patterns, with high "glass" gloss. The only rim tapes to reflect sunlight!! ALL reflective materials will tend to look more intense in pictures. Camera flashes can be more intense in a split second than other lights. LEGAL in most places since they are made for SAFETY and are NOT lights!! These are NOT "glow in the dark." RIM SIZE FOR BICYCLES Please be aware that the numbers on your bicycle tire is the tire size, not rim size, so you must follow these instructions to find your actual rim size: Measure the diameter of your rims, NOT tires, from edge to edge. Your measurement will always be UP TO 1" more than your actual rim size. For example, your measurement of a 22.1" to 23" diameter, means you have 22" rims. Therefore you should be ordering a 22" size rim tape. Also, rim tapes can only be applied to rims with disc brakes since you CANNOT have the pad brakes rub on the rim tapes. RIM SIZE FOR MOTOR VEHICLES (i.e. cars, motorcycles, etc.) The last two digits in the numbers imprinted on your tires is your rim size. For example, "180/55ZR17", means you have 17" rims.
