Customer Review: Adequate
This rack got my two, fairly heavy mountain bikes through a 900 mile road trip without breaking. I was a little concerned; it doesn't look all that sturdy, but it managed. It said it works with Jeep Wranglers, which it does, but it's a bit of a squeeze around the third brake light. Product is galvanized on the outside, but not on the inside. The first time it got rained on, rusty water drained from the tubing. It did the job though, and was a reasonable price.
Customer Review: Be careful to not buy older version
I just purchased the SR1, as advertised here on Amazon and on Hollywoodracks.com. However, it is NOT the one in the photos on either site. The one in the photos has, I discovered, support arms that are new for 2007. Their part number is SR1-SA2 and they have the cradle and rubber straps to set the bike frame in. The prior support arms simply have a dip in the arm where you set the frame, so you have to figure out some other way to keep the bike from bouncing off the support arms. That part number is SR1-SA.

Apparently Hollywood Racks did not think to distinguish the new from the old model because they are both SR1. So, be careful what you buy because I'm not sure there is a way to tell which you are getting unless you open the box, since the model number is the same for both. (Looks like a convenient "mistake" that allows Hollywood to unload older merchandise on consumers!)

As to how the bike rack works -- not sure I'm going to even keep it, so can't say yet. Click for more details ...
