Nice tire so far. I got 38mm, they measure 39.5 on my wheels. They roll a little better on the pavement that the last tires I had. Mounted easily with a pump with the tubeless booster on it.
I was looking for something that was fast rolling on the pavement and was able to ride on the hard packed gravel roads. I only run the SS on the rear and I run the SK on the front.
