A secure rack - tricky to install
The Thule Sidearm is a very good rack. I have been using it for about a month and it holds my rood bikes securely to the hood of my car with-out any front-end wind-induced wiggling.
It was however not easy to install and I found I had to reverse the installation sequence of the rear roof clamp and the rear wheel fastener - not easy since the rack had already been secured to my roof bars.
I also find that the "sidearm" which secures the front wheel is stiff and takes some elbow grease to move about.

well worth it!!
Why did I buy the item through Amazon from out of US? Yes, that's what people wonder. I would say one thing, it's worth buying from Amazon.com. We can trust, fast responce, and easy to buy. Whatellse do we need? Besides, the item also doesn't exist in Japan, no one has it. It's cool I am may the only one who has it.. hehe. Thnx for everything.

Outstanding!!!
This is one of the easiest racks to use. It takes seconds to install the bike. I think it is worth the extra money. The only issue is smaller person may have a problem lifting the entire bike on the roof.

One fine Thule
I was a bit hesitant to put this carrier on my car. It's only an old integra and I thought it may look a weird have a full bike on top. Well I'm glad I did purchase it, no longer do I have to take the front wheel off my bike. It's just lift on the roof, ratchet, and strap and away I go. It doesn't look too bad. the carrier is sturdy, my bike is not fly off the roof. When the rack is not in use it does have a large profile even when it's folded down. All I need now if for Thule to design a roof rack for an integra that allows you open the moon roof. Come on Thule get it together.

World's Quickest Bike Rack
I got this bike rack specifically to hold my son's BMX bike. I coughed at the price, but it seemed to be the only one designed to specifically handle BMX-sized bikes. Assembly was straightforward, as was mounting to my Thule rack (it will fit other systems as well).

Mounting the bike literally requires about 30 seconds. You put the bike on the rack, slide the ratchet arm down on to the wheel/fork, strap the back wheel, and you're done. I was really impressed with how solidly the simple ratchet arm holds the bike. There is no play at all. Releasing it is just as quick.

We also have a short garage, but this only adds about 3" on top of the rack when it's folded down, so our van still makes it into the garage.
