Comments about Thule Sidearm 594XT:

This product is terrible. I have a set of black aeroblade bars on my blacked out GLA45 AMG and within seconds of setting this carrier to mount, the threads of the bolts started to chew away at the black pain! Who designs their product to destroy the pieces it interfaces with during the install??
In addition to this ludicrous design, the slope in my roof line prevents the rubber mounting adapters from making a clean and flush interface with the aeroblade bar. Clearly Thule did NOT consider that not every car would have a flat roof...because well we actually live in 1978 and aerodynamics hasn't been invented yet.
I'd also like to nominate the first person to properly assemble a side arm bike carrier on their first try as the next supreme leader of the human race and crown them genius of the millennium generation...*$^%@# is it ever confusing! I read every page in the instruction manual and nowhere does it specify how to correctly select the carriage bolt sizes to go around the aeroblades....oh wait except for on page 12 where it recommends the large 80mm bolts as a blanket suggestion.
For the benefit of those reading this review, I am currently on my 3rd day of attempting to fit this to my car after work so I can go out and enjoy a ride, but the shear number of configurations that are possible but not idea will leave doctoral mathematicians in a combinatorial quandary. Here is the final setup that I have acheived after a seriously unnecessary strugggle:

Dual mounts below the rotatable locking arm:
1a. In front of the forward load bar: a 65mm carriage bolt.
1b. behind the forward load bar: a 65mm carriage bolt.

2a. In front of the rear load bar (mount that utilizes the underside track): an 80mm carriage bolt.
2b. Behind the rear load bar: a 65mm carriage bolt.

See the photo of the rear bar and the destruction caused by the carriage bolt threading on this nice example of SOMEONE ELSE's silver aeroblade bar. Imagine how much WORSE my bar looks being black

Comments about Thule Sidearm 594XT:

Well, I've been a lifelong Thule fan until now. I received the sidearm as a gift a year ago. Somehow the lower tire bar has significantly bent which now tilts the bike 15% when on the rack...not good. I attempted to get a replacement, even just the $5 part thru Thule's awesome lifetime warrantee. Now I'm told by them that it's not covered as I'm not the original purchasing customer and ownership has been transferred. Are you kidding me? Well Yakima is looking better all the time. Thule apparently doesn't care about my bike falling off the rack nor the liabilities? Boo!

Comments about Thule Sidearm 594XT:

I use this rack on my car with every bike my family owns from the kid's 20" bikes to my 29er and everything in between. I can install and remove this rack from my car in less than 5 minutes. It doesn't take a genius to figure this thing out. My only complaint is the decals on the plastic end caps fell off after over a years worth of usage.
