Another new bike, so another set of those reflective wheel stickers. I've tried cheap and expensive materials that come in rolls that claim to be reflective intended to increase safety and they've all failed in one way or another. I'll be honest on a very egregious downside to this product that in daylight it's freaking ugly on the face if you examine it closely. There's a whimsical geometric pattern that breaks up the color pretty thoroughly, I don't see a need for it for functionality. ANYWAY THEY ARE NOT JUST REFLECTIVE THEY ARE REFLECTIVE REFLECTIVE no matter what angle the light hits them as they are just flat stickers they reflect the light straight back and scatter a bit in the general direction so photos of one Blitz looks like neon lights mounted on bikes. Just get them, if you don't like the look of the rim stripes, get the black ones. Not as bright reflection, but still better than no reflection
