Slapped some new tires on the KVS last night. First time doing the job. It definitely took far longer than it should have, but it was also very cold and the rubber was not in a giving mood. I used Continental Road Attack IIIs and it completely changed how the bike rides and maneuvers. I was a little skeptical after balancing the wheels and tires. No weights... Although, only the front wheel had a 1 oz weight on it with the old tire.
