Product Description: Carry your Tandem or LWB recumbent on your standard roof rack. The Bike Topper can take bikes with up to a 76" wheelbase and singles too. The tray is even coupled so you can remove the long tail section when not in use. Elevated fork mount for low-rider pannier and disc brake compatibility. The Topper includes 2 separate wheel straps so you can leave one in place for your regular bike, and one where you need it for your long bike. Compatible with Thule and Yakima crossbars.
