When we're packing bags and planning logistics for a four-person, cross-country trip to a storied desert trail system, there's a whole lot of snack money to be saved by expanding our rack's carrying capacity with Kuat's NV Base 2.0 2 Bike Add On. This accommodates everyone instead of shelling out gas for a whole extra car to tote those two extra bikes. Expanding your 2-bike NV Base 2.0 into a 4-bike capacity, this add-on features adjustable cradles that accommodate wheelbases up to 48-inches and tire sizes ranging from skinny road slicks up to 4.8-inch fat tires. It also includes integrated cable locks for peace of mind at travel day cafe stops.Expand your NV Base 2.0 hitch rack's capacity to four bikesIncludes individual bike cable locksCompatible with separately sold Trail Doc
