I installed my 13" Madstad windshield yesterday on my 2016 Road Glide. I've got to say that the customer service and the product is top notch. In the past I've had to purchase at least several windshields before I found what worked for me. When I got this new bike, I did a lot of research and decided to bite the bullet and get the best shield on the market. I was not disappointed. I haven't dialed it in yet, just set it where I thought it needed to be and went for a ride. There is no buffeting at all and no negative pressure behind the windshield. This will be the only shield I'll own for now on. I just wanted to say thanks to Mark and the crew at Madstad for the excellent product.
