So far the bike rack has been up to Jasper National Park from Boulder, CO with stops along the way in Grand Tetons, YellowStone, Glacier, Banff and Lake Louise National Parks as well as a roadtrip from Boulder to Toronto, ON through Missouri, Kansas, Kentucky, Tennessee, Ohio, Illinois and Michigan. I've gone on various road conditions over the 5,000+ miles as well as in various driving conditions (city, highway, off roading, and country).
This bike rack is incredibly easy to use. It is what I call "micro adjustable" just because the bike is clamped to the rack with a bunch of slide-able wheel wells and tire arms adjustable at any position. It works with any bike type, and is super easy to install - no special tools needed. Your car just needs either a 1.25" or 2" hitch.
I also love that it comes with included, retractable bike locks to secure your crappy or expensive bikes to the rack, then another lock between the rack and your car's hitch. I can't fully open my trunk (although it looks like the new model EX2 solves this bit of trouble) when I have bikes on the back, which I would complain about if this didn't take any longer than 30 seconds to get the bike's off.
I was also impressed how well the rack held up when I went up Shadow Mountain with 2 on the rack to do some riding around the summit with the Grand Tetons as my backdrop. The bumpy road and constant rocking could've bent the frame, but it held up beautifully.
Shout out to Saris for putting some good material around the wheel clamps to keep any harsh contact points against my bike. My bikes are cheap, but someone with anything they care about will appreciate the care they took to keep their bike protected.
I'll do an update on this review after a few more weeks with the rack for my overall impressions, and so far so good!
