The Blinder MINI Chippy, so called because of the Chips on Board technology used giving a panel of light. The reflective face and surface mounted LEDs punch well above their weight, outputting 11 lumens of rear light, keeping riders seen and visible up to 800m away.  With a weight of only 18 grams the light uses its tool-less attachment to securely connect to seatposts 22–32+mm including aero style seatposts.
