Packing the car for a trip can feel like a challenging game of Tetris. Simplify the process with the CURT quick-release bike mount accessory, designed to pair perfectly with the CURT 18123 roof rack cargo carrier (sold separately). This handy accessory lets you securely store bicycles outside your vehicle, freeing up space for other gear. It’s compatible with 9mm, 12mm, and 15mm bike forks and is built to last with durable 6061 aluminum sleeves and a corrosion-resistant, zinc-plated steel clamp.
