The Vertex hitch rack's unique arc design makes it easier to load and unload, provides better ground clearance and gives you greater distance between your bikes for easy transport. Hitch Switch feature allows you to tilt the mast down and away for easy rear of vehicle access.
Do you have a frame with a unique shape that doesn't have a traditional top tube? Are you worried it won't fit on a rack like the Vertex? Well worry no more. Thule makes the Thule Frame Adapter just for bikes like yours.
