That seems odd since I'm 5' 11" (32 inseam) and could barely see over a 17 inch shield. When I was relaxed the edge of the shield was right in my line of sight. Drove me nuts. I guess that shows we all sit different on the bikes. I'm using a 15" shield right now and it seems just right. I'm still experimenting before I spend anymore money on shields. Thanks for your input!
