It’s kinda funny how such a simple thing can bring such joy to people. Yeah, a 40c tire. It’s bigger than a 35c but not as big as a 45c. It’ll fit just about any production cross frame. WTB calls it a gravel tire, but that tread looks like it’ll rip up some 1-track just fine.
Here’s the scoop:
“WTB Nano 40c tires will be available in Race and Comp versions starting April of 2014. Nano 40c Race tires will feature a folding Aramid bead, Lightweight Casing, DNA Rubber, weigh in at 470g, and retail for $49.95. Nano 40c Comp tires will feature a wire bead, Durable Casing, DNA Rubber, weigh 550g, and retail for $31.95.”
