I'm not totally convinced. Just purchased a KlockWerks 6 1/2" Flare for my SG. Although it certainly looks good not sure it performs as great as it's supposed to perform. My initial ride was disappointing but maybe there was more of a crosswind than anything else. We'll see after a few more rides.
I must say adding the klockwerks 8.5 to my 14 SGS was a great addition to a great bike. Relieved fatigue in neck on long rides and eliminated vision problems in cross winds for mrs on two up rides. Buffeting was terrible.
