Quick Loading and Convenient!
this Thule 599XTR Big Mouth review by JulZ
vehicle year/make/model: 2009 Honda Accord 4-door
item(s) transported: bicycles
The design of this rack is great, compared to my old axle mount this is way quicker and more convenient. I don't know why I ignored this type of rack previously, maybe I was too used to the axle mount or the price. This is a bit more money but I feel it's justified with convenience. I bought two of them and have them mounted on a Thule rapid aero rack bars. I also bought the Thule Xadapt2 for the quick release bolts which slide into the aero racks' t-slots easily and cinch down securely. Really a clean look. When you close the jaws it has a piece that prevents access to the quick release bolts. Everything locks either with or without a bike in the rack so you can leave for your ride and know the rack will still be there when you get back. Neat! The jaws are easy to use just put the bike in the tray, hold the downtube with one hand while bringing up the jaws with the other, snap the lever down and lock it. Then you strap the tires normally and go. Feels very secure. If you're looking for a convenient roof-mounted bike rack, this is one I am very happy with.

Alison asks - How many lock cylinders will I need to purchase for this rack? Going by the description it seems like two. Is this correct?
ORS Crew answers - Sorry for the confusion, this bicycle carrier requires only one lock for security, which simultaneously locks the bike to the carrier and the carrier itself to the roof rack.
B. Demaris asks - Just bought from you guys a second Thule 599XTR Big Mouth bike rack. When I mount the rack to the bars they are in opposite directions. How can I get the front end of both bikes to point forward? Must be something simple?
ORS Crew answers - Yes see page 2 of the Thule 599XTR Big Mouth installation instructions. You need to just loosen the base of the bike frame holder assembly and slide it forward on the bike tray and position it so the front edge of the base on the bike frame holder assembly is 12 inches (30.5cm) from the end of the bike tray. Then retighten.
