                        I really like the design with the LinQ ready sides. I purchased the additional LinQ latches and this thing is rock solid. I also purchased the PRP bag to go on top. This is by far the best way to carry tools, parts, etc. while on my multi day rides or just going out for the day. With my OEM tire rack, I can see out the rear view mirror! Oh, and customer service is excellent.
