Why settle for boring wooden or stone coasters when you can have a set of Crank Coasters. These coasters come in a variety of colors and are designed to look like a bicycle crank.
Currently money is being raised so that these Crank Coasters can go from being just a cool concept to a reality. I'm not a huge cyclist, but I know more than a few people who would be happy to show off their love of their fixies with these Crank Coasters. If you build it, they will come.
