Here's a picture, I have been raising the seat up to eliminate knee pain. The drop is just an estimate but I have a 31.5" cycling inseam and the frame is 19.5". I'm only 5'9" so I didn't think a 21.5" frame made sense. I've thought some sort of stem raiser + some 1.5" riser bars that I could rotate to tweak seat-to-bar length would do the trick.
