It's been a few years since I have been able to long haul a bike run. Knowing that I was going to return from this 2012 trip and see my back surgeon 2 days later had me worried. I was loading my bike when a good friend and neighbor stopped over. I have suffered for more than 7 years, and my friend Henry amongst others questioned my ability to do the ride. Then he went home to get something that he said and I quote,"I've got something you have to try". This was by far the best thing anyone has ever done for me. The Airhawk not only "Saved My Ass" but it renewed my passion for the ride. I could not go more than 150 miles in a day and with this miracle product under my butt, I pulled some serious mileage each and every day.It worked so well that my back didn't start hurting until I was home for a couple days. I am still in need of fusion of 4 vertebra, but I am confident that I'll be back in the saddle in no time. There are products that make claims and then there are those which make promises. The Airhawk is a "No B.S" product that works. I am ordering mine today and got home only 2 days ago.
