Garson Fieldswrote a review of WTB Nano TCS Light FR Tire - Clincher on November 29, 2016
Familiarity: I've put it through the wringer
These things are sweet. They're grippy on dirt, roll fairly fast on pavement, and they'll shrug off some serious hits without flatting. It was painless setting them up tubeless on WTB i19 Asym rims with one layer of Gorilla tape. They're not the longest lasting tire, and the 40mm size will be too big for most race-focused 'cross bikes, but they're absolutely worth running if they suit your intended use.
