With 70 lumens of power, five modes and up to 20 hours of run time the Knog Blinder Road R70 rear light is bright enough to be seen from over 1000 meters away. Despite all this performance, this light is also incredibly hardwearing too. Being 100% waterproof and designed with a composite and alloy case, this light is well protected from the elements as well as heavy-handed bike riders. Like many Knog lights, this has an inbuilt USB pin, meaning it plugs straight into your computer to charge – no cables, no fuss. By including several silicone straps with this light, Knog has also ensured that the Knog Blinder Road R70 rear light can fit on a variety of different seat posts with ease. 70 Lumens 5 modes Weight: 75g Visible up to 1000 metres 20 hour maximum run time 5 hour charge time Integrated USB rechargeable battery Low battery indicator 100% waterproof Replaceable silicone strap
