The X-Board plays the same role for your front wheel as the X-Blade does for the rear -- it's a nicely basic fender to protect you from water spray off of moist (but not water-logged) roads. It mounts in a matter of seconds to the underside of your frame's downtube with a tool-free grommet system. Ideal for riding/commuting in areas where the roads are wet in the morning, but it's not actually rainy out. 99g, Black only. Folks normally pair the X-Board with the X-Blade to get comprehensive protection from the elements.
