The BikeSmart BarNone Frame Adapter is an ingenious solution for carrying bicycles that don't have standard top tubes on rear-mounted car racks. The heavy-duty, spring-loaded clamps attach to the bike at the stem and seatpost, creating an effectively straight top tube to suspend from the car rack. The frame adapter works with most step-through frames (low-step, mid-step) and kid's frames.

• For use with racks where bikes are secured by the top tube, such as hanging style hitch racks, trunk racks or home bike storage solutions.

• Minimum seat tube to stem distance: 18"

• Maximum seat tube to stem distance: 28"

• Bike weight capacity: 35 lb
