Got a Grip?

I got my new S-Works Fast Trak tires just in time for the Skyline Park Mountain Bike race this weekend. I went with a beefier 2.2" in the front and a 2.0" for the rear. I've had them before, but just in the front. I noticed the difference between these and the Renegades instantly, more grip and the roll just as fast. I can feel the slight weight gain, but in all honesty I'd rather make up time descending with more confidence and speed than chugging up a hill. Check back to see how they performed.
