Review on Ho Stevie! Surfboard Bike Rack - Conveniently Transport Your Surfboard to the Beach [Available in Different Colors] by James Roberts

Overall this mount works pretty well but the main downside is the part you attach to the seatpost isn't tight enough. The corner of my 8ft longboard starts to shift so my rear tire starts rubbing against it even with the bolts tightened as tight as possible. Manufacturers should really try to fix this with rubber washers or something to increase friction, or change the design entirely to prevent shifting. My only other complaint is that I think there should be a simpler mechanical design for mounting the holders. Light spring pins can be used instead of screws, which is much faster and easier.
