Dunlop Bike Helmet with Light - Bike Helmet Women and Men - Adjustable from 55 to 58 CM - Bike Helmet Size - with LED Lighting - 3 Light Modes - Black

ADJUSTABLE BIKE HELMET - The Dunlop bicycle helmet is adjustable to a diameter of 58 to 61 centimetres. You can adjust the helmet by using the knob to loosen or tighten the internal ring in the helmet. CYCLE HELMET WITH CHIN STRAPS - When the bike helmet is on your head, attach the chin straps. These should also be firmly attached. When the buckles are closed and you open your mouth, the strap should press against your chin. It should not be possible to remove the bicycle helmet without undoing the chinstraps. BICYCLE HELMET TO PREVENT INJURIES - If you are a keen cyclist or road racer it is important to wear a good helmet at all times in case you have an accident or fall. The Dunlop helmet is specially designed to absorb the energy of a fall and therefore drastically reduce head injuries. CYCLING HELMET WITH LED LIGHTING - The Dunlop cycle helmet therefore features a large reflector on the back of the helmet. This reflector contains 6 LED lights that make you visible to other road users in bad weather and in the dark. DIFFERENT LIGHT MODE - Choose to have the lights on at the same time, blink them slowly or set them to a fast blinking mode. This ensures that you stand out from other road users when cycling in the dark. The LED lights work on 1 CR1620 battery that is included with the bicycle helmet.
