So I’ve found 3 sets of 7700 bar end shifters but one set is on Paul thumbie mounts, one on SJS thumbie mounts and one is the levers without bar end mount. I know that last set has mounts, but I used them on a bike with downtube shifters mounted to them instead. I’ve since stripped that bike so can pair up the mounts and shifters for you. I’ll do that and take some photos for you tomorrow.
