and this time it was correct, no flaws. The Corbin is a big firm, and I will have to go for a long ride to get a better sense of it. I liked the cupped contour, and the better back support ( even without the additional back rest ). It is a bit wider, and I sit a bit higher. I also got my footboards installed. It will take some getting used to. I only rode for 20 miles, so my feel for them is limited. But, I can tell that I like the way I can find so many positions for my feet. I can see the big benefit.
