K60's are capable of a quick pace but certainly not a fast pace. They square off pretty quick then suck at transitioning in curves. Great tire for multi-surface tour. I tried to keep up with Freak and Fredz in MO on a used up K60 rear and found my limit well before they did ::025:: Brick I think I know how you ride ::26::Brick said:There is a group I ride with that are... lets say spirited and well I love it. So could not do K60's for that riding at all! Other than that I would love to try the K60's
