Specialized Resolution 2.1
After removing the packaging, the tire weighed in at 565 grams. I think that's awesome for a high volume aggressive tire. After mounting the tire, I noticed that the 2.1 is actually smaller than last year's 2.0. I got the ruler out and found that it was still pretty tall compared to the other 2.1's I had in the garage. The knobs are taller this year, and the center knobs are ramped for less rolling resistance. It has a 120 tpi casing, an aramid bead, and dual rubber compound. The center of the tire has a harder rubber compound, while the shoulders have a softer compound for increased grip in turns. I picked the tire up for around $30 at a local shop.
I'm using the Resolution as a rear tire. The tire performs well in a variety of conditions, and rolls quickly thanks to the tread design and lightweight construction. As expected, the higher volume smooths out the bumps on my hard tail. I'm running about 32 PSI of pressure, and there is no danger of pinch flats for XC riding conditions.
I haven't tried it as a front tire, but I know a couple people that didn't like last year's tire in the front. Maybe with the increased knob height of the 07, it'd work ok in the front. I think Brent is using this tire front and rear...maybe he'll comment!
Update: After riding this tire for a couple months I've come to the conclusion that it excels as a rear tire. The center knob configuration felt a bit sketchy for front tire use. I've found that a staggered knobby configuration works best in the front. The WTB Weirwolf and IRC Trail Bear work very well as front tires in my conditions. For rear tire use, however, the Resolution is awesome! Very light, high volume, great climbing and braking traction. Another rear tire that I like is the WTB Mutano Raptor 2.4. This larger tire has clearance issues on some frames though. The Resolution is a good solution for running a taller tire on frames with tight clearances.
