The Kuat Transfer seems to be among one of the cheaper "No Frame Contact" platform hitch racks available. It's also one of the lightest at 20lbs for a single tray.

The downside? It's limited to 47" wheelbase.

For comparison's sake - a Guerrilla Gravity Revved Smash Size 4 has a wheelbase of about 50".

Anybody know if there is a way to fit longer wheelbase bikes on the Transfer?
