For all 37mm and wider gravel tires, WTB is implementing its new SG2 Puncture Protection and a 120tpi casing to “keep up with the demands of modern gravel riding,” which has been getting progressively rougher and longer. The new SG2 Puncture Protection consists of a lightweight nylon insert that provides bead-to-bead coverage for more defense against punctures. According to WTB, lab tests have shown the new insert provides 33% more sidewall protection and 17% more tread protection than WTB’s standard 60tpi offerings without SG2. As an added bonus, the SG2 layer is so tightly woven that it improves air retention, reduces sidewall seeping, and helps maintain tire pressure between rides.

“Rather than simply adding a layer of puncture protection to our 60tpi gravel tires and calling it good, we set out to increase durability while also improving ride quality and minimizing weight,” explains Clayton Wangbichler, WTB’s product marketing manager. “Not willing to settle for anything less than optimal, we analyzed lab test data and put thousands of miles on a myriad of different casing and puncture protection configurations before we finalized our current specifications.”

The new gravel tires are available exclusively with black sidewalls and only see a weight increase of 5-10% (15-50 grams) over their 60tpi counterparts without puncture protection. The standard 60tpi gravel tires are still available with an MSRP of $59.95, while all SG2-protected 120tpi gravel tires have an MSRP of $69.95 USD. The entire gravel tire line—including the ByWay, Venture, Riddler, Nano, Sendero, etc—is currently in stock and can be ordered from your favorite local bike shop or on WTB’s website for cyclists in the USA.
