Bed racks with removable rear crossbar?

Hey guys. Do you know what brand the pictured rack is or other brands that have an easily removable rear cross bar for loading dirt bikes or other tall items? I'd also like the rear of the rack to sit forward a bit to make it easier to load mountain bikes on a tailgate pad. I only know of the Leitner rack, which is a bit fancier and pricey than I need.

 

I run the KB Voodoo rack, and carry bikes frequently. The bars are removable and you can place them as far forward as you'd like - they mount in the rails on the bed sides. (for mine at least). I had to do some trial-and-error fitting because I also run a tonneau (it is compatible with the cover), and had to set them so the mounts didn't interfere with the tonneau and also could open the last fold without too much trouble.

 

You're talking about bed crossbars, but I think he wants an overland style rack with removable crossbars.
