Für alle, die wieder mal die grauen Straßen bunt einfärben möchten: Contrail ist ein Kreide-Marker fürs Fahrrad. “Contrail is a small bright bike accessory that allows bicyclists to color in their own space on the road. It’s like playing with sidewalk chalk, but faster. Contrail holds 200 grams of chalk, enough for about 20 miles (32km) of riding. It functions much like a carpenter’s chalk line: A small amount of powdered chalk is filtered through a brush inside the device and picked up on a felt wheel. The felt wheel transfers this chalk onto the rear tire leaving a fine layer. As chalk builds up, the tire leaves a faint line of color on the roadbed. This is you contrail. It is a colorful and ephemeral representation of your path.” Via
