Oddly, the Vulpine isn’t as fast a rolling tire on gravel which is loose, chunky, and deep as other tires with similar width. However; once you get out of situations where the terrain is loose and deep, the Vulpine begins to show up as a fast, controllable tire.
WTB has some really good non-puncture protected gravel/all road tires in their line, but there was no puncture protected version, until now. The SG2 gravel tires seem to be a good addition to the range as long as you understand that the width indicated on the side wall may not match the width of the tire in reality.
This was the model I was most concerned about going into this review. Since the standard Resolute is still my #1 gravel tire, I was really hopeful that the SG2 model would at least approximate what I liked about this tire.
