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 tire isn’t a ‘bad’ tire, but for the MidWest it isn’t a tire that lights a fire underneath me when I ride it. It does the job well enough, sure, but with its slightly harsher ride quality and lack of volume, it isn’t on the same plane as the Resolute or the Byway, both of which we are testing in this series of SG2 reviews.
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.
WTB tire users on the mountain biking side may recognize the “SG” as being a reference to “Slash Guard”. That would be about the only similarity here though as “Slash Guard 2” is a new technology and is currently only offered on WTB’s gravel tire range.
This would make a very nice option for your gravel bike on that second set of wheels, the one you run for faster days on paved roads. Of course, the 30mm version is that as well, but this bigger version takes things up a notch when dirt or truly bad roads are on tap.
I have to say that these are compelling tires for mixed surface riding in our So Cal conditions. The casing size is just enough, the tire is fast, it rides well, and has some side knobs for increased grip on looser corners. I like them very much.
