Absolutely. As I read it, designer of One Up has gone on to produce this with X impovements. Probably not groundbreaking changes compared to someone who already owns a One Up. But, nice by my standards of convenience etc.
I believe that Küat has a rack or 2 with ramps.The only racks that have integrated ramps are the ones from Thule and Yakima. The 1up has an available ramp but it is short, prevents using their license plate holder, it does not securely attach to the rack and flips over with wide tires, and as it is only 3" wide it does not work with wider fat tire bikes. I bought a Motorsports folding motorcycle ramp for my 1up Super Duty double rack.
