We use Jakroo and they fall about 4-5 inches above the knee for me in an XL (and I'm 6'3"). They're comfy bibs and the company allows you to order as many or as few as you want and at whatever time frame you want (great if you need a crash replacement or have newcomers to a team) with a 2 week turn around time. The only downer that we all saw last year was that the cuffs around the legs stretched a bit during the year. The 2014's have been good so far, but it is still June.

I have some Louis Garneau bibs that are suprisingly long and I hate them. I don't wear them often, but when I do I can feel the material make contact with the back side of my knee and upper calf with each pedal revolution. Blah.
