Super killer new pattern! These are designed to fit either 700c or 650B wheel sizes as the stays are adjustable. Made from a base of Walnut with inlay polka dots made from Cherry, Wenge, Maple, and Blood wood to which creates a "Planetary look". These are insane! Fender width is 1 3/4" to fit tire sizes up to around 42c. Be the first earthling in your galaxy to own these as there's only one set available.
