Power to the Pedal Finalist - Contrail

Give your ride some color... or Give your slower cycling buddies some idea where you went after you dropped them... You Decide...

THE CONTRAIL: 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.

How it works: 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.
