Helping out the friend in need or fitting your third stage-race rig onto your existing 2-bike Kuat rack, the NV Base 2. 0 Add On supplies one additional tray for easy bike transport. Identical to the base trays, the Add On maintains an integrated aesthetic with matte black powdercoating. The "in-tray" cable lock keeps the bike secure, and the adjustable tire cradles pivot up or down to accommodate wheelbases of up to 50 inches.
