Fitment Note: Bike must come equipped with a quick release front skewer. This carrier is not compatible with fork dropouts less than 5/32" (4mm) or greater than 13/32" (10mm) thick, and the dropouts must be 3 15/16" (100mm) apart. This carrier is limited to bikes weighing no more than 37.5 lbs. No more than 2 Circuit carriers can be mounted to a factory rack.

Today's active lifestyles and demanding enthusiasts require products that are easy to use, perform as promised, and look good in the process. The Circuit Roof Bike Rack delivers on all counts. The Circuit is the perfect bike rack for the cyclist that's always on the go. It loads and unloads quickly, without tools, and provides the security and stability necessary to ensure your bike transports and arrives safely. The Circuit is also ideal for the enthusiast who wants more than just functionality. The Circuit, with its AeroHead low-profile reinforced head, will complement whatever vehicle it's mounted on, with a combination of aerodynamics and style.

The SecureSkewer secures the bike's forks quickly and easily. Just place the fork dropouts onto the skewer, and then tighten the ratcheting nut until the skewer lever closes with some resistance. The skewer can be locked with a Thule One-Key lock cylinder (sold separately). The rear wheel rests securely in the integrated wheel cradle, with a high wall design that provides added protection and the perfect fit beneath the wheel. A ratcheting strap quickly and gently secures the rear wheel to the cradle. Both mounting points are attached to a "D" shaped low profile aluminum tray made from corrosion-resistant aluminum to withstand the elements.

The Circuit attaches to all Thule rack systems, round bars and most factory racks, without the need for any tools. To keep your trunk clutter free, we recommend that you transport your front wheel on the roof with the Thule Wheel On wheel carrier (sold separately). A Thule roof carrier protects your bike from road dirt better than hitch or trunk racks. And the stable and secure roof rack attachment also gives you the versatility to add other accessories to the base rack.
