A year or so ago, I had mentioned that I wasn't fond of the kenda nevegal/blue groove, which I had the Nevegal up front and the Blue Groove on the back, and the bike felt off. It was pointed out that I had the combo backwards, didn't really believe it, but finally decided to try the tire combination again. This time Blue Groove up front, Nevegal in the back. After a couple of rides on them I was wrong, I am impressed. The combo rides and handles extremely well. So please excuse me while I eat some crow.
