This is a rear rack from the German carrier manufacturer "TUBUS/チューブス". It is lightweight and very durable. It is also compatible with disc brakes and can be easily installed with the included skewer. Material: Chromoly Color: Black Distance from the center of the eyelets to the top plate: 375mm I purchased this new and used it for about six months. It was stored indoors and attached to a bike that was not ridden in the rain, so there is no rust, but there are some minor scratches from use. Please understand that this is a used item before purchasing.
