We have 2018 N models and have put Madstad shields on both. It really helps with the wind at freeway speeds. My wife and I are the same height, but she has a longer inseam. For my wife, the Madstad site measurement directions said 20" shield. I tried it out and still got buffeting around my helmet. I just bought the 24" shield, and it is much improved. That said, you're still going to get wind.
