Hi, I just bought my Swing about two months ago and love it except for the seat height. I received my Corbin two weeks ago and I figure it's about 1.5 inches lower than standard. When I ordered it they ask for your height, weight and inseam.
As my inseam is only 27.5 I needed all the help I could get!
Anyway, I'm really pleased with it and I can almost flat foot in tennis shoes. I don't seem to have lost any comfort. The only problem, which you get used to, is that they cut down the "nose", their term for the front of the saddle. First time I stopped a bit quickly I slid forward.
Other than that it's great, very pleased.
Good luck!
