The original Kaffenback has V-brakes, not discs, and enough clearance for mudguards with most tyres (not with my Nokian Hakkapeliitta studded tyres though), although one of the mountings for the mudguards was using screws into the underside of the rear brake bridge, which may have been deleted on your frame (I can't really tell from the photos).
My Kaffenback has straight handlebars, but that wasn't a choice, the discounted kit came with straight ones, so that was what I used. The Kaffenback geometry seems to be much the same as the One-On Pompino, only that frame obviously doesn't have the rear changer hanger. Given this frame's disc brakes, I'd guess that it throws any comparisons into the Pompetamine court!
I quite like the sand colouring of my Kaffenback, but black always looks good, and works with anything (especially on a Night Ride!)
