I could break my bikes down and squeeze them in the back but this is so much easier. Anyone else try this Seasucker rack yet. I've owned 7 different racks over the years every time I change cars seems my rack isn't compatible. But this set up will attach to anything.
Having used high-quality suction cups as a glass installer, I've seen how much force they can generate. They do have to be very high-quality (I would assume these are) and have a vacuum pump built-in, preferably with a device which would allow you to check/monitor/increase the vacuum from inside the car (I can see something going from the rack into the passenger compartment?)
Using that set-up would be scary at first, but as long as the install was clean and the cups were well maintained I can definitely see it working very well.
They aren't suction, they are vacuum, and yes, I had one of these racks. They work very well. Taken at 80mph on the highway, even though it looks like I am parked. Cellphones take pretty good pictures these days...
