Jack I have lowers that will fit the upper tubes as well as they ones for the lower tubes. They were a special acquirement from Memphis Shades that you can not get outside of them directly.
If you go with upper tube mounts you have to buy the complete set plus the additional clamps. If you go lower tube you get changes in the length of the mount bracket. That is why I have the upper and lower tube application so you can choose which you like.
Also, option as I posted in a review, the other option you have is to remove the upper fork tubes and then a few other options open up.
I was right in the middle of a trial for Memphis Shades application and my supplier went out of business and I am waiting to re-establish that link. But Slipstreamer Classic screen functions really well with this set up and is still on my bike! Great performance and the look is good too without the shrouds. This screen however is NOT quick release ad in my critical assessment will not NEED lowers.
