This rear deck bike carrier breaks all conventional thinking. Most rear deck bike carriers conform to the back hood of your car through adjustments made in a "Hub" system and support your bike with two support arms.
This system accomplishes all the adjustment necessary with 4 concentric rings that follow and engage the bent tube frame at various intervals. An internal pin system locks the support arm in place as the pin penetrates an array of punched holes in the interior wall of the tubing.
An additional cradle can be permanently mounted to the bike frame. When its time to go simply slide the cradle onto the support arm and go. "More photos on the way"
